Question

in the figure given below​

Answer 1

Answer:

<STU = 70*

Step-by-step explanation:

let the point of intersection between the two rays QR and ST be A.

so, <PQR = <SAR (corresponding angles of || lines PQ & ST)

and similarly,

      <SAR = <STU (corresponding angles of || lines QR & TU)

from bot equations, we get-

=> <PQR = <SAR = <STU

=> <PQR = <STU

<PQR is 70*, as given. so-

=> <PQR = <STU = 70*
