2. m∠Y by definition of obtuse angle
3. ∠C ≅ ∠A by definition of congruency
4. ∠N and ∠P are complementary angles by definition of complementary angles
Step-by-step explanation:
1. The given parameters are;
Statement [tex]{}[/tex] Reason
ΔABC is a right triangle [tex]{}[/tex] Given
∠A is a right angle [tex]{}[/tex] Given
m∠B = 45° [tex]{}[/tex] Given
m∠A + m∠B + m∠C = 180° [tex]{}[/tex] Sum of interior angles of a triangle
m∠C = 180° - (m∠A + m∠B) [tex]{}[/tex]
m∠C = 180° - (90° + 45°) = 45° [tex]{}[/tex] Substitution property
m∠C = 45° = m∠B [tex]{}[/tex] Substitution property
∠C ≅ ∠B [tex]{}[/tex] Definition of congruency
2. Statement [tex]{}[/tex] Reason
m∠X = 4·a + 2 [tex]{}[/tex] Given
m∠Y = 21·a + 3 [tex]{}[/tex] Given
∠X and ∠Y are linear pair [tex]{}[/tex] Given
m∠X + m∠Y = 180° [tex]{}[/tex] Sum of angles of linear pair
4·a + 2 + 21·a + 3 = 180° [tex]{}[/tex] Substitution property
25·a + 5 = 180° [tex]{}[/tex]
a = (180 - 5)/25 = 7
m∠Y = 21 × 7 + 3 = 150° [tex]{}[/tex] Substitution property
m∠Y = 150° > 90
m∠Y is an obtuse angle [tex]{}[/tex] Definition of obtuse angle
3. Statement [tex]{}[/tex] Reason
∠A and ∠B are complementary angles [tex]{}[/tex] Given
∠A + ∠B = 180° [tex]{}[/tex] Definition of complementary angles
∠B and ∠C are complementary angles [tex]{}[/tex] Given
∠B + ∠C = 180° [tex]{}[/tex] Definition of complementary angles
∠B + ∠C = ∠A + ∠B [tex]{}[/tex] Transitive property
∠C = ∠A [tex]{}[/tex] Reverse of addition property of equality
∠C ≅ ∠A [tex]{}[/tex] Definition of congruency
4. Statement [tex]{}[/tex] Reason
ΔMNP is a right triangle [tex]{}[/tex] Given
∠M is a right angle [tex]{}[/tex] Given
∠M + ∠N + ∠P = 180° [tex]{}[/tex] Sum of interior angles of a triangle
∠N + ∠P = 180° - ∠M [tex]{}[/tex] Subtraction property of equality
∠N + ∠P = 180° - 90° = 90° [tex]{}[/tex] Substitution property of equality
∠N + ∠P = 90° [tex]{}[/tex] Substitution property of equality
∠N and ∠P are complementary angles [tex]{}[/tex] Definition of complementary angles.

The sum of 3 consecutive numbers is 72. What is the largest of these numbers?
23
25
26
28
Answer:
25
Step-by-step explanation:
23+24+25=72
hope i helped!! :)
( if it is right, pls mark brainliest!!)
Answer:
25
Step-by-step explanation:
let x represent the first consecutive number.
let x+1 represent the second consecutive number.
let x+2 represent the third consecutive number.
x + x+1 + x+2 = 72
3x + 3 = 72
3x = 72 - 3
3x = 69
3x/3 = 69/3
x= 23
first number= x = 23
second number = x+1
= 23+1
=24
third number= x+2
=23+2
=25
the largest of these numbers is 25

Triangle FUN, with vertices F(−2, 4), U(0, −5), and N(−3, −8) was dilated to form triangle PET with vertices P(−1.6, 3.2), E(0, −4), and T(−2.4, −6.4).Which scale factor was used? A. 1.25
B. −1
C. 2/3
D. 0.8
Suppose these statements about two triangles are
true:∠G=∠S,∠R=∠,and ∠M=∠N. Which statement is correct? Select all that apply.
A.The sides are congruent.
B.The sides are proportional.
C. ΔGRM is similar to ΔNST
D. ΔMGR is similar to ΔNST
Answer:
For first question answer is D.0.8
For second question answer is D.ΔMGR is similar to ΔNST.
Step-by-step explanation:
Here triangle FUN is dilated to get triangle PET
So, let's take F and P.
F(-2,4) and P(-1.6, 3.2)
Let's find the scale factor by dividing the coordinates.
Scale factor =[tex]\frac{-1.6}{-2} =0.8[/tex]
Using y coordinates of the same points
Scale factor =[tex]\frac{3.2}{4} =0.8[/tex]
So, scale factor is 0.8
Now, for the second problem
<G= <S
<R= <T
<M=<N
So, the corresponding angles are congruent when two triangles similar.
So, we can say ΔMGR is similar to ΔNST.
what is the slope of the line that goes through the points (2,-1) and (6,1)
Answer: The slope is [tex]\frac{1}{2}[/tex].
Step-by-step explanation:
1. You set up your Slope Formula [tex]M=\frac{y2-y1}{x2-x1}[/tex].
2. Substitue your points into the formula.[tex]M=\frac{1--1}{6-2}[/tex].
3. Once you substitute, you will solve the equation[tex]M=\frac{2}{4}[/tex].
4. Simplify the equation if you have to [tex]M=\frac{1}{2\\}[/tex].

What is the equation in point slope form of the line that passes through the point (3, 1) and has a slope of –2?
Drag and drop the appropriate number, symbol, or variable to each box.
Answer:
y = -2x + 7
Step-by-step explanation:
you can use y–y1=m(x–x1) but I just plug straight into y=mx+b and solve from their (much simpler)so plugging the numbers in y=mx+b it will become 1 = -2(3) + bsimplify so 1 = -6 +b or b – 6 = 1add six to both sides to get b=7slope or m is -2 and b or y-intercept is 7y= -2x+7Find an equation for the line with slope m=4/7 and which goes through the point (21,-7)
Answer:
y=4/7x-19
Step-by-step explanation:
So the equation is :
y-[tex]y^{1}[/tex]=m(x-[tex]x^{1}[/tex])
m= slope
y+7=4/7(x-21)
y=4/7x-19

Step-by-step explanation:
The density of gold is 19.3 grams per cubic centimeter. Rachel determines that the density of a coin is 18.7 grams per cubic centimeter. Based on this evidence, she concludes that the coin is not gold or at least not entirely gold. Is this an example of inductive or deductive reasoning?
Answer:
The reasoning is a deductive.
The reason is because the pattern of thought is logical, here, scientific methods ( i.e mathematically obtaining and comparing the density of the coin and the gold ) are used to support the conclusion.
Step-by-step explanation:
Gnerally the reasoning is a deductive.
The reason is because the pattern of thought is logical and scientific methods (eg mathematical equation (formula for density)) are applied to arrive at the conclusion.

Miss Bloom's 5 $45.30 on art supplies if she turns 7% tax how much total money did she spend
Answer:
l
Step-by-step explanation:
Answer:
Miss Bloom spent $48.47 in total
Step-by-step explanation:
turn 7% into a decimal --> 0.07
multiply the cost of art supplies by the tax % (in decimal form)
45.30(0.07) = 3.171
add 3.171 to the original cost of art supplies
45.30 + 3.171 = 48.471
round to the nearest hundreths place (since money typically only has 2 decimal places)
48.471 --> 48.47
therefore, miss bloom spent $48.47 in total

Integrated math 2 NEED HELP ASAP
Answer:
56
Step-by-step explanation:
Since the 2 triangles are congruent, the ratio of their sides are also equal. Therefore, we can set up an equation:
[tex]\frac{10}{16}=\frac{3x+2}{5x+1}\\\frac{5}{8}=\frac{3x+2}{5x+1}\\5(5x+1)=8(3x+2)\\25x+5=24x+16\\x=11[/tex]
Now that we know x, we can plug in x as 11 into the expression of DE to solve for DE:
5*11+1
=56
