Question

Find the value of x in the picture below(round to nearest test)

Answer 1

x = 13

Explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² = 5² + 12² = 25 + 144 = 169 ( take the square root of both sides )

x =
`√(169)` = 13
