Question

What is X??? Please find x??????

Answer 1

Since the triangle is a right-angle triangle,

Using Pythagoras Theorem,

x^2 + x^2 = 8^2

2(x^2) = 64

x^2 = 32

x = √32 or - (√32)

However, since x is a positive value,

x = √32

Sorry, I don't have a calculator with me right now, but if you want the exact value of x expressed to 3 sig. fig., you can type √32 into a calculator and find out
