Question

In the figure, find angle PRS , angle PTS , angle RTS , angle PRQ
​

Answer 1

Answer:

PRQ=100°, PRS=80°, RTS=55°, PTS125°

Answer 2

Answer:

For angle PRQ

angle pqr + angle prq + angle qpr = 180° (angle sum property)

50 + angle prq + 30 = 180

angle prq = 180 - (50+30)

= 180 -80

= 100°

For angle PRS

angle prs + angle prq = 180 (linear pair)

angle prs = 180 - 100

angle prs = 80°
