​

Answer 1

Answer:

please mark me as brainliest.......

Step-by-step explanation:

m <a = 180°-[m< Q +m<P].......... measure of a

= 180°- [60° + 55°]. triangle is 180°

= 180°- 115°

= 65°

m< a +m<b =180°

65°+ m<b =180°

m<b = 180° - 65°

= 115°

m<b +m< R +m<c = 180°

m<c = 180° - (m<b +m<R )

= 180°- (115°+ 40°)

= 180° - 155°

= 25°
