Question

Find the missing length indicated

Thank you

Answer 1

100

Explanation:

y is the length from top left to the shaded line from the top

z is the length from top left to the shaded line from the bottom

the shaded line = 48 (we are using Pythagoras theorem in this step and all the following ones)

48²+y²=z²

z²+60²=x²

48²+y²+60²=x²

x=y+36

48²+60²=72y+1296

y=64

x=100
