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°
