Answer:
<em>The helicopter is 27.38 m far off the ground</em>
Step-by-step explanation:
The drawing shown in the image below has all the measures and variables needed to solve the problem.
We need to find R, the height of the helicopter. We'll use the law of sines to find the length of side a.
The angle X is the measure needed to complete 180°:
X = 180° - 54° - 62° = 64°
Solving for a:
Calculating:
a = 31.11 m
Now using the sine ratio in the right triangle to the left side:
Solving for R:
R=31.11*0.88
R = 27.38 m
The helicopter is 27.38 m far off the ground
Let the measure of the complementary angle be x so that the measure of the other angle is 14x. The total measure of the angles is 180 degrees. Thus, one angle measures 12 degrees. The other angle measures 14*12=168 degrees.
P(non-conforming and complete inspection) = 0.08 x 0.55 = 0.044
P(conforming and complete inspection) - 0.92 x 0.2 = 0.184
P(complete inspection) = 0.044 + 0.184 = 0.228
P(non-conforming|complete inspection) = 0.044/0.228 = 0.193
the answer is 0.193 or 19.3%
