Question

With steps pls Full answer​

Answer 1

Step-by-step explanation:

straight line makes angle 180 degrees so angle PQR is 40 degrees

Answer 2

Step-by-step explanation:

1. Procedure 1

140 +/_ PQR= 180° ( linear equation)

/_PQR=180°-140°

= 40°

1. Procedure 2

sum of interior Angles = opposite exterior angle

/_PRQ +/_ RPQ= 140° (EQ. I)

/_PQR+/_RPQ+/_PRQ = 180 (angle sum property of a ∆)

/_ PQR + 140 ( as per EQ. I ) =180 °

/_PQR= 180 -140

= 40°
