Find all three angles of the triangle x-5 x+10 x-35
Answer:
See below ~
Step-by-step explanation:
Given : 3 angles of a Δ
(x + 5)°(x + 10)°(x + 15)°Solving :
According to Angle Sum Property of a triangle, the angles of a triangle add up to 180°x + 5 + x + 10 + x + 15 = 1803x + 30 = 180x + 10 = 60x = 50Finding the angles
x + 5 = 50 + 5 = 55°x + 10 = 50 + 10 = 60°x + 15 = 50 + 15 = 65°There are 32students in categories a and b combined.24are in a and 24 are in b. how many are in both a and b
Answer:
16.
Step-by-step explanation:
48 - 32 = 16
So there are 16 in both category a and category b.
8 will be in category a only, and 8 in category b only.
Total = 8 + 8 +16 = 32.

What is the area, in square units, of a trapezoid bounded by the lines $y = x$, $y = 10$, $y = 5$ and the $y$-axis? express your answer as a decimal to the nearest tenth
The area of a trapezoid is bounded by the lines y = x, y = 10, y = 5, and the y− axis is 37.5 square units.
What is the area of the trapezium?A trapezium is a quadrilateral having two opposite sides parallel.
The area of a trapezium is equal to;
[tex]\rm Area =\dfrac{1}{2} \times \text{Distance between the parallel sides} \times \text{Sum of the parallel sides}[/tex]
The trapezoid is bounded by the lines y = x, y = 10, y = 5, and the y− axis.
The vertices are at (0,10), (10,10),(5,5) and (0,5)
You need to find the area of the rectangle (0,10) (10,5) (0,5) and (5,5)
The lengths are 5, 5,5,5.
The area of the legs is = 5 × 5 =25
The area is;
[tex]\rm Area =\dfrac{1}{2} \times \text{Distance between the parallel sides} \times \text{Sum of the parallel sides}\\\\Area =\dfrac{1}{2} \times 5 \times 5\\\\Area =12.5[/tex]
And the right triangle (10,5),(5,5), and (10,10) the right angle is at (10,5)
the two legs are lengths 5 and 5
so together they are 25 +12.5=37.5 square units.
Hence, the area of a trapezoid is bounded by the lines y = x, y = 10, y = 5, and the y− axis is 37.5 square units.

−4≤4x+8
(With explanation, I'm confused because I keep getting x≤−3 when the solution is x≥-3.)
Step-by-step explanation:
To solve the inequality:
4x + 8 ≥ -4
4x ≥ -12
x ≥ -3
If this is what you did then I'm not sure how you ended up getting x ≤ -3. You're not dividing by a negative number so the sign never switches.
Hope this helps
Step-by-step explanation:
−4≤4x+8
Subtraction property of inequality with the value 8.
-12≤4x
Division property of inequality with the value of 4.
The reason the sign stays as less than or greater to is because the sign only switches when the DIVISOR is negative, not the dividend.

Which set of side lengths forms a right triangle?
O 2, 3, 13
O 4, 6, 10
O 9, 12, 18
O 15, 36, 39
Which one is correct? I'm getting told two different things. Find the value of x
Answer:
x ≈ 25.7
Step-by-step explanation:
using the tangent ratio in the right triangle
tan65° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{12}[/tex] ( multiply both sides by 12 )
12 × tan65° = x , then
x ≈ 25.7 ( to the nearest tenth )

solve the system by elimination for 2x-y=11 and 6x-3y=15
The system of equation has no solution.Because the variables in the given equation got canceled during substation.
How can we determine the solution to an equation?We do the identical actions on both sides to ensure that both expressions remain equal. Solving equations entails determining the values of the variables involved for which the equation is valid.
The given equation is;
Equation 1;
[tex]\rm 2x-y=11[/tex]
Equation 2;
[tex]\rm 6x-3y=15[/tex]
From the equation 1 find the value of the y and put in the equation 2 as;
[tex]\rm y=2x-11[/tex]
[tex]\rm 6x-3y=15 \\\\\ 6x-3(2x-11)=15 \\\\\ 6x-6x-33=15[/tex]
From the above equation, it is observed that the variables in the equation got canceled.

Find the area of a triangle with vertices A(0, 2), B(8, 2), and C(4, -3).
Answer:
20
Step-by-step explanation:
First, consider (0,2) and (8,2). The y-value is the same for both points. x ranges from 0 to 8, so the length of this horizontal side of the triangle is (8-0), or 8.
Again, this horiz. side has a y-value of 2.
The third point is (4,-3). Therefore the vertical distance from the horizontal line to the third point is 2 - (-3), or 5.
Thus, the "base" of the triangle is 8 and the "height" is 5.
The area is A = (bh)/2. Substitute the values 8 and 5. Simplify your result. Answer: 20 square units.
