Since angle of depression = 72°54 minutes.
60 minutes = 1°
54 minutes = 54/60 = 0.9°
Therefore 72°54 minutes = 72° + 0.9° = 72.9°
Since angle of depression = 72.9°, the reverse angle of elevation = 72.9°
(Picture representation of this using right angled triangle is needed)
tan 72.9° = Opposite height / Horizontal distance
tan 72.9° = 1191 / x
x = 1191 / tan 72.9 Use a calculator.
x ≈1191 / 3.2506
x ≈ 366.39
Horizontal distance ≈ 366.39 feet.
Hope this helped.
1/x = x^-1
sqrt(x) = x^(1\2)
Therefore, answer is:
x^(-1/2)
Tan(34) = a/700
a = 700*tan(34) =472.155 so 472
Answer:
the answers are 783 and 786
62 inchezzzzzzz so 60-4 = 56 --- 56 +6 = 62
