Answer:
C. 24.1 ft
Step-by-step explanation:
The side of the wall making the tilt of 75° will represent the hypotenuse
The height of the wall will be represented by the side opposite to the angle 75°
Apply the relationship for sine of angle Ф
Formula to use is ;
Sin Ф= length of opposite side÷hypotenuse
SinФ=O/H
Sin 75°=O/25
0.96592582628=O/25
O=0.96592582628×25 =24.1 ft
True because of 15 and 20
