Question

1. How do I find Angle PQR?

Answer 1

Answer:

90

Step-by-step explanation:

draw a line parallel to AB or CD through Q .

now angle PQR divides into 2 parts .

we get each part in each case .

case 1 :: newly drawn line is parallel to CD . Then part of angle PQR and 35 degrees angle are alternate interior angles . as we know alternate interior angles are equal one part is 35 degrees .

case 2 :: newly drawn line is parallel to AB . Then other part of angle PQR and 125 degrees angle are co interior angles . As we know cointerior angles are supplementary . other part of angle PQR is 55 degrees .

adding those 2 parts gives us angke PQR as 90 degrees.

Answer 2

Step-by-step explanation:

180-(55+35)

=180-90

= 90°
