Question

in a triangle ABC,AB=AC. IF Angle B=30°,what is the measure of angle A​

Answer 1

Answer:

the answer will be 120

Step-by-step explanation:

ab=ac

a+30=a+c

120+30=120+30

Answer 2

Answer:

120⁰

Step-by-step explanation:

in the triangle ABC, IF AB=AC

Angle B= Angle C

Angle B = 30⁰

Angle C = 30⁰

sum of all the angles in a triangle is 180⁰

30⁰+30⁰+ x = 180⁰

60⁰+ x = 180⁰

x = 180⁰-60⁰

x = 120⁰

Angle A = 120⁰
