Answer:
The ladder reach a height 8.485 ft.
Step-by-step explanation:
The ladder with the building made right angle triangle
The length of the ladder is the hypotenuse 12 ft.
The angle between the ladder and the building is 45°
The height of the ladder reach is the vertical side of the Δ
∴ h = 12 cos 45° = 6√2 = 8.485 ft.

Answer:
x = 97.6
Step-by-step explanation:
cos = adjacent over hypotenuse

* multiply each side by x *

* divide each side by cos ( 55 ) *

we're left with x = 97.63302055
Our last step is to round to the nearest tenth of a foot
We get that x = 97.6
