Answer:
1035.33 feet
Step-by-step explanation:
OBH is a triangle and the sum of the angles of a triangle = 180
∠OBH = 90°
∠OHB = 180 -(49 + 90) = 41°
The law of sines that the ratio of each side of a triangle to the sin of the angle opposite it is the same
Thus
A/sinα = B/sinβ = C/sinγ
where A, B and C are the three sides of the triangle and α, β, γ corresponding respectively to the angles opposite them.
Using the law of sines

Therefore BH which is the height the helicopter is flying at is

≈ 1035.33 feet

Answer: The student's estimate is off by 12%
Area = length x width
x² + 12x = l * x
A. First, you factor x from x² + 12x

area = x (x+12)
area = (x+12) * x
Length = x + 12
B.If
x = 10,l = x + 12 = 10 +12 = 22
length = 22
and
Area = x² + 12x = 10² + 12(10) = 100 + 120 = 220
area = 220 Hope this helps :)
