Answer:
78.92
Step-by-step explanation:
Before we get x we need to calculate ED which will help to get x later
Using pythagoras theorem
99.2^2 = 62^2 + ED^2
9840.64 = 3844 + ED^2
9840.64 - 3844 = ED^2
ED = square root 5996.64 = 77.44
112^2 = 77.44^2 + (×+2)^2
12544 = 5996.64 + (×+2)^2
12544 - 5996.64 = (×+2)^2
(×+2)^2 = 6547.36
×+2= sqr root (6547.36) = 80.9157586629
× = 80.9157586629 -2 = 78.9157586629= 78.92ft aproximately
