Answer:
we have a right triangle and to get the internal angle of the right triangle formed at the helicopter we subtract 62 degrees from 90 which equals 28 degrees
we now use the cosine to find the distance (d) from the helicopter
cosine 28 = 85/d
d = 85 / cosine 28 = 85 / 0.8829 = 96.2736 = 96 feet
Answer:
As shown in picture, shaded space area:
A = outer rectangle area - inner rectangle area
= 11 x 8 - 9 x 6
= 88 - 54
= 34 (yd2)
Hope this helps!

Answer:
b = 2A/h
Step-by-step explanation:
The formula for area of a triangle is
A = 1/2 bh where b is the base and h is the height
We want to find the base
Multiply each side by 2
2A = 2*1/2 bh
2A = bh
Divide each side by the height
2A/h = bh/h
2A /h = b
b = 2A/h
