Question

1. In APQR, PR=cm, QR= a m, PR=b mand ZR= 90°. Write down an expression for tan(P), Draw the
triangle as well.
Solution:​

Answer 1

Answer:

Given: PQ=10cm, PR=24cm

Let QR be x cm.

In right angled triangle QPR,(Hypotenuse)2=(Base) 2+(Perpendicular) 2 [By Pythagoras theorem]

⇒(QR)2=(PQ)2+(PR)2⇒x2 =(10)2+(24)2

⇒x2

=100+576=67⇒x= 676

=26cm

Thus, the length of QR is 26cm.
