Question

Pythagorean Theorem pls help :P

Answer 1

x =
`√(84)`

Explanation:

According to Pythagorean Theorem, the square value of hypotenuse is equal to sum of square value of two legs:

x^2 + 4^2 = 10^2

x^2 + 16 = 100 subtract 16 from both side

x^2 = 84 find the root of both sides

x =
`√(84)`
