Question

solve this problem in brief. ​

Answer 1

Step-by-step explanation:

given : PQR=PRQ

and ST is the straight line

Now...

let the PQR = x =PRQ

So....

the degree of straight line is = 180°

From here the equation forms:

PQS+x =180 =PRT+x

PQS+x=PRT+x

We can cancel the x of both side

HENCE ......

PQS+x-x=PRT

Therefore....

PQS=PRT
