Question

please solve this I want it please solve and please solvev in step by step please ​

Answer 1

Step-by-step explanation:

a)in ∆PQR

<PRQ=<SRT=40-----VERTICALLY OPPOSITE ANGLES

PQ || ST and QS is the transversal

<PQR=<TSR––– ALTERNATE ANGLES

<PQR=60

b)in∆RST,

BY ANGLE SUM PROPERTY,

<R+<S+<T=180

40+60+<RTS=180

<RTS=80
