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:
123,458,798
Step-by-step explanation:
The first is 6.1 using the distance formula.
distance = sqrt((x2-x1)^2+(y2-y1)^2)
plug it all in and simplify
you get 6.1
the next one is the midpoint. u just take add both values of x together and divide by 2 to get the x coordinate and then add together both values of y and divide by 2 to get the y value. the midpoint is (8,7)
to find the perimeter of the rectangle, add the lengths of each side. 25 for the height and you would add 2 of those and then there are 2 sides as long as the length that you would add. it would be height+height+length+length which is 25+25+77+77=204. remember units so 204 ft
