Question

Find the missing side
Please help with

Answer 1

x = 4
`√(3)`

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 , then

x² + 4² = 8²

x² + 16 = 64 ( subtract 16 from both sides )

x² = 48 ( take square root of both sides )

x =
`√(48)` =
`√(16(3))` =
`√(16)` ×
`√(3)` = 4
`√(3)`
