What is the length of QR?

Elena L [17]

Answer:

Step-by-step explanation:

Since the triangle is right with hypotenuse QR

Use Pythagoras' identity to solve for QR

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

QR² = 8² + (8 $\sqrt{3}$ )²

= 64 + 192

= 256 ( take the square root of both sides )

QR = $\sqrt{256}$ = 16
