Question

In triangle PQR , <Q = 90° , find QR ; if PR = 25cm and PQ = 20cm.
answer fast guys help step by step explanation​

Answer 1

Its so simple suse just use pythagoras theorem

if yet you do not understand then go through below provided solution

Answer:

15 cm

Step-by-step explanation:

PR=25 pythagoras theorem

PQ=20

pr²=pq²+qr² hypo²=perpendicular ²+base ²

25²=20²+qr²

625-400=qr²

225=qr²

therefore qr=square root of (225)

so qr=15 cm ans
