What Is The Length Of Side PR A 8 Cm B 11 Cm C V105 Cm D V176 Cm E V274 Cm class=

Sagot :

Answer:

D. √176 cm

Step-by-step explanation:

Were given a right triangle.

PQ = 7 cm

QR = 15 cm

To find the length of side PR, apply Pythagorean theorem, which is c² = a² + b²

Where,

c = hypotenuse/longest side = 15 cm

a = PR

b = 7 cm

Thus:

15² = PR² + 7²

225 = PR² + 49

225 - 49 = PR²

176 = PR²

√176 = PR

PR = √176 cm
