Question

Find the x in PQR, please

Answer 1

13

Explanation:

As the given triangle is right angled, we can use Pythagoras theorem to find hypotenuse

Base² + Perpendicular² = Hypotenuse²

PQ² + RP² = RQ²

(12)² + (5)² = x²

144 + 25 = x²

169 = x²

x = √169

x = 13.

Answer 2

Answer is A

Explanation:

Use the the pythagorean theorem

x=√12²+5²

x=13
