Question

In a triangle ABC, AB = AC and <B is two times of <A ,then what is <A,<B and <C ?​

Answer 1

Answer:

angle a=90 angleb = c =45

Answer 2

Answer:

Step-by-step explanation:

given:

ab=ac

so, abc is an isosceles triangle

if b is 2 times of a then c is also 2 times of a

so , let the measure of (angle a) be x

angle sum property of a triangle is 180

so

x+2x+2x=180

5x=180

x=180/5

x=36

so measure of (angle a) = 36

measure of (angle b) = 72

and measure of (angle c) = 72
