Question

in the given figure show that angle a equals to Angle B + angle C if angle a = 100 degree and Angle B is equals to 55 degree find angle C
​

Answer 1

Answer:

angle(a)=angle B +angle C

angle a= 100 , angle B = 55

angle C = 45

Answer 2

110° ,75° ,48 °

Step-by-step explanation:

∆B +∆C = ∆A

60° +50°=110°

∆A =110°

∆A-∆B=∆c

130°-55°=75°

∆c= 75°

∆A-∆C=∆B

108°-60°=48°

∆B = 48°
