Question

A 22-ft ladder leans against a building so that the angle between the ground and the ladder is 73°. How high does the ladder reach on the building? (Round your answer to the nearest foot.)

Answer 1

21 ft

Explanation:

From the diagram attached ,

sinθ = opposite/Hypotenus

sin73° = h/22

Where h is the height from where the ladder touches the building

make h the subejct of the equation

h = 22sin73°

h = 22(0.956)

h = 21.03

h = 21 ft (to the nearest foot)
