Question

The second question.....please solve

Answer 1

Answer:

Step-by-step explanation:In triangle PQS, angle PSQ = 45 and angle SPQ = 180 - (90+45) =45

So as both the opposite angles are equal PQ= SQ =x

tanR=tan30= PQ/QR

1/√3= x/10+x

10+x/x=√3

10+x= √3x

(√3-1)x=10

x= 10/√3-1

On rationalizing,

x=5√3+5

So,

PQ=5√3+5

RQ=5√3+15
