Answer:
279.62 feet
Step-by-step explanation:
We have a rectangle with 5ft x 305ft sides representing the area between your device and the base of the courthouse.
In addition to this we have an angle of 42 °
The height would come being the length of the opposite side of this triangle.
We know that:
tan (° A) = opposite / adjacent
Adjacent side is 305 ft and ° A is 42 °
Solved for opposite:
Opposite = adjacent * tan (° A)
Opposite = 305 * tan (42) = 274.62 feet
We must add 5 feet to this result and we are left with:
274.62 + 5 = 279.62
It means that the height is 279.62 feet
