Question

In Triangle ABC,AC=BC and angle A = 100° then find angle B​

Answer 1

Answer:

40

Step-by-step explanation:

Triangle ABC = 180 degree

A = 100

B= ?

C= ?

A.T.Q.

100+x+x =180

100+2x =180

2x = 180-100

2x =80

x = 80/2

x = 40 Ans

Answer 2

Answer:

AC = BC

angleA + angleB + angleC = 180

angleA=100°

100+angleB+angleC = 180

angleB+angleC = 180–100

angleB + angleC = 80

angleB = angleC

angleA=100° , angleB= 40° , angleC = 40°

just we want only angle B

AngleB=40°
