Question

a ladder 30 decimeters long is leaning against the side of a building. the ladder makes an angle of 25 degrees with the side of the building. how far up from the ground does the ladder touch the buildings?

Answer 1

H=how far up from the ground does the ladder touch the building
h/30=sin 25°
h=30 sin 25°
h=12.7 decimeters(1 decimal place)
Answer: The height that the ladder touch the building far up from the ground is 12.7 decimeters.
