Question

exercise 8.1 class ten maths solution question number 3​

Answer 1

QR² = (13)² -(12)²

QR² = 169 -144

QR² = 25

QR = 5

Tan P = 5/12

Cot R = 5/12

Tan P - Cot R =0

Answer 2

We have to find tanP - cotR

First use the pythagoras theorem in triangle PQR

QR= 5 cm

tanP = QR/QP = 5/12

cotR = QR/PQ = 5/12

5/12 - 5/12 = 0
