Can someone’s please help
Fiesta28 [93]

Answer:

4.87 ft

Step-by-step explanation:

The height of the skylight =

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

Let <em>b</em> ft be the height of the blue △.

sin 60° = \frac{b}{25}

<em>b</em> = 25 sin 60°

Let <em>r</em> ft be the height of the red △.

tan 40° = \frac{r}{20}

<em>r</em> = 20 tan 40°

The height of the skylight

= 25 sin 60° - 20 tan 40°

= 4.87 ft (rounded to the nearest hundredth)
