Answer:

4.87 ft

Explanation:

The height of the skylight =

The height of the blue △ - the height of the red △

Let b ft be the height of the blue △.

sin 60° =
(b)/(25)

b = 25 sin 60°

Let r ft be the height of the red △.

tan 40° =
(r)/(20)

r = 20 tan 40°

The height of the skylight

= 25 sin 60° - 20 tan 40°

= 4.87 ft (rounded to the nearest hundredth)
