Question

Please solve it


In triangle ABC, Angle B is equal to Angle C and Angle A is equal to 100°
Find angle B ​

Answer 1

Answer:

A=100°

B=x

C=x

A+B+C=180°

100°+x+x=180°

100°+2x=180°

180°-100°=80°

80°×2=x

40°=x

B=40°

Answer 2

Answer:

angle B is 40 so. therefore angle C is 40

Explanation:

angle B = angle C

so,

angle A + angle B + angle C =180°

100 + angle B + angle B = 180° ( angle B and C are equal )

2 angle B = 80

angle B = 40

so , the ans is,

angle A = 100° , angle B = 40° and angle C = 40° ( don't forget to put degree )
