URGENT AT LEAST TAKE A LOOK A 16 ft ladder is propped up against a building at an angle of 52°. How far up the wall does the ladder go?

A) 12.6 ft
B) 25.9 ft
C) 9.9 ft
D) 20.3 ft

A. 12.6 ft

Step-by-step explanation:

Using sin because of opposite over hypotenuse, you can find x.

sin(52) = x/16

16sin(52) = x

Plug it into your calc.

x = 12.6082

And you have your final answer.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
