Question

PQR is a triangls,right angled at P.If PQ=10cm and PR=24cm,find QR​

Answer 1

Answer:

QR = 26cm

Step-by-step explanation:

By Pythagoras Theorem

QR^2 = PQ^2 + PR^2

QR^2 = 10^2 + 24^2

QR^2 = 100 + 576

QR^2 = 676

QR^2 = 26^2

QR = 26

Answer 2

Answer:

By pythagoras theorem,

• QR²=PQ²+PQ²
• QR²=(10)²+(24)²
• QR²=100+576
• QR²=676
• QR²=(26)²
