Answer:
237.65 feet
Step-by-step explanation:
From the diagram attached,
Let the height of the blimp above the ground be h
From triangle A of the diagram,
tan18° = (360-y)/h
h = (360-y)/tan18°..................... Equation 1
Also
From triangle B in the diagram,
tan50° = y/h
h = y/tan50°.............................. Equation 2
Equation equation 1 and equation 2
(360-y)/tan18° = y/tan50°
tan50°(360-y) = tan18°(y)
1.19(360-y) = 0.325(y)
428.4-1.19y = 0.325y
428.4 = 0.325y+1.19y
1.515y = 428.4
y = 428.4/1.515
y = 282.8
Substituting the value of y into equation 2
h = 282.8/tan50°
h = 282.8/1.19
h = 237.65 feet.
Three common tangents is illustrated when two circles touch each other externally at one point and they'll have three tangents.
<h3>How to illustrate the information?</h3>
It should be noted that a common tangent simply means a line the bus tangent to more than one circle.
In this case, three common tangents is illustrated when two circles touch each other externally at one point and they'll have three tangents.
A diagram is attached to illustrate the tangent.
