y=5.4
Step-by-step explanation:
So first we cross multiple.
2*112=35*(y+1)
224=35y+35
-35 on both sides
189=35y

What would be the SUM of the lengths of the first and second diagonals rounded to the nearest whole number?
Answers
Answer:
16 m
Step-by-step explanation:
Use Pythagorean theorem,
hypotenuse² = base² +altitude²
= 5² +6²
= 25 + 36
= 61
First diagonal = [tex]\sqrt{61}[/tex] = 7.81 m
Second diagonal² = first diagonal² + altitude²
= [tex](\sqrt{61})^{2}[/tex] + 3²
= 61 + 9
= 70
second diagonal = [tex]\sqrt{70}[/tex] = 8.37 m
First diagonal + second diagonal = 7.80 + 8.37 = 16.17 = 16

6,\ 12,\ 12\sqrt{2}
Step-by-step explanation:
The required values of the x, y, and z in the given triangle are 26√3, 13√3, and 39×√2 respectively.
If you know the lengths of two sides of a right triangle, you can use trigonometric ratios to calculate the measures of one (or both) of the acute angles.
Here,
For triangles,
sin45 = 39/x
z = 39×√2
xsin60 = 39×√2 cos45
x ×√3/2 = 39
x = 39 × 2 / √3
x = 26√3
Now,
cos60= y / x
1/2 = y / 26√3
y = 13√3
Thus, the required value of the x, y, and z in the given triangle are 26√3, 13√3, and 39×√2 respectively.

Right angled triangle. To find the hypotenuse, use Pythagorean theorem.
Hypotenuse² = base² + altitude²
= 6.5² + 2.7²
= 42.25 + 7.29
= 49.54
hypotenuse = √49.54 = 7.04 = 7
Step-by-step explanation:
by using Pythagoras law
h²=p²+b²
missing angle =h let
h²=(2.7)²+(6.5)²
h=√(49.50)=7.03=7
Line t intersects line u as shown below
What is the value of x
Answers
Answer:
x = 117 degrees
Step-by-step explanation:
Find the diagram attached
From the diagram, the angle at the top left on line t is equal to theta of the top left on line u and is equal to 117 degrees (corresponding angle)
Also the angle angle on the top left on line u will be equal to x (vertically opposite angle)
Hence the value of x = 117 degrees (vertically opposite to each other on line u)

D)
BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°
Answers
Answer:
D)
BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°
Step-by-step explanation:
15²-12² = 9²
BC = 9
sin B = 12/15 = 0.8
∠B = 53.1°
The solution will be BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°. The correct option is D.
What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the sum of the square of the other two sides.
The triangle ABC is a right triangle. The new path is in front of the right angle, therefore it is the hypotenuse. To find the length of the hypotenuse we use the Pythagorean theorem:
H² = P² + B²
The length BC will be calculated as below:-
15²-12² = 9²
BC = 9
The angle B will be calculated as below:-
sin B = 12/15 = 0.8
∠B = 53.1°
Therefore, the solution will be BC = 9; m∠A = 36.9°; m∠B = 53.1°; m∠C = 90°. The correct option is D.

Step-by-step explanation:
Given the 2 equations
y = - 2x - 4 → (1)
y = 4x + 2 → (2)
Substitute y = 4x + 2 into (1)
4x + 2 = - 2x - 4 ( add 2x to both sides )
6x + 2 = - 4 ( subtract 2 from both sides )
6x = - 6 ( divide both sides by 6 )
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (2)
y = 4(- 1) + 2 = - 4 + 2 = - 2
solution is (- 1, - 2 )

if 3 kilograms = 6.618 pounds how many pounds are in 3 grams
Answers
Answer:
0.00661 pound
Step-by-step explanation:
If 3 kilograms = 6.618 pounds than There are approximately 0.006636 pounds in 3 grams. To convert grams to pounds, we can use the given conversion factor: 3 kilograms = 6.618 pounds.
First, we need to convert 3 grams to kilograms. Since there are 1000 grams in a kilogram, we divide 3 grams by 1000 to obtain the equivalent value in kilograms:
3 grams / 1000 = 0.003 kilograms
Now, we can use the conversion factor to convert kilograms to pounds. Multiplying the equivalent kilograms (0.003) by the conversion factor:
0.003 kilograms * (6.618 pounds / 3 kilograms) = 0.006636 pounds
Therefore, there are approximately 0.006636 pounds in 3 grams.
