Question

Please answer this question ​

Answer 1

Answer:

according to Pythagoras law

pq²+qr²=pr²

25=pr²-qr²

25=(pr+qr)(pr-qr)

25=25×(pr-qr)

pr=qr

hence q is not equal to π/2

Answer 2

Step-by-step explanation:

pq = 5 cm

pr = 25 - qr

but by pythagoras theorem,

pr2 = qr2 + pq2

(25 - qr)2 = qr2 + 25

625 - 50qr + qr2 = qr2 + 25

600 = 50qr

qr = 12 cm

pr = 13 cm

sin P = qr/pr = 12/13

cos P = pq/pr = 5/13

tan P = qr/pq = 12/5
