Question

In triangle point s is the midpoint of side QR if PQ is equal to 11 PR is equal to 17 PS is equal to 13 find QR

Answer 1

Answer:

Step-by-step explanation:

In right ΔPQR,

we have

PQ=11 units ,PR=17 units ,SR = ? ,PS=13 units

By Apollonus's Theorem,

2) Since S is the mid -point of QR.

=> QR= 2*SR = 2*6 = 12 units
