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° = 
<em>b</em> = 25 sin 60°
Let <em>r</em> ft be the height of the red △.
tan 40° = 
<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)

Answer:
84 tickets
Step-by-step explanation:
So first off lets add the tickets we sold to the tickets we have left. Lets x equal the amount of tickets we started with before selling.
25+17=x
Add them up.
42=x
We started with 42 tickets. To find how many tickets we had before spiting the tickets. We need to multiply our tickets by 2 since we had half. Let y be this number
42*2=y
Multiply them up
84=y
We started with 84 tickets.
