Answer:
Explanation:
1. Imagine a triangle with base side 36 feet and Kate at the right with the angle of elevation, 24 degrees. We can use tangent:
tan 24 = o/a ; tan(24) = o/36 ; 36(tan(24)) = o ; o = 16 feet
This is how tall the screen is.
2. We do a similar operation:
tan(74) = o/a ; tan(74) = 555/a ; a = 555/tan(74) ; a = 159.1 feet
Hope this helps!
