Question

In an isosceles triangle ABC, AB=BC if A= angle 52 degree , what is the measure of angle B.

Answer 1

sum of all angles of a triangle = 180°
angle a + angle B+ angle C. = 180°

Angle B = angle C ( Base angles of an isosceles triangle are equal).
Let angle B an c be x° each.

52° + x° +x °. = 180°
2x °. = 180° - 52°
x. = 122° /2
x. = 61°

Ans.= Angle B is 61°.

Answer 2

Lets use angle sum property
that is  angle A+ angle B+ angle C= 180*

So Let Angle B and C Be X degrees

we known that angle A= 52 degree

so the solution is 

52+ x+x=180
2x+52=`180
2x=180-52=128

so x=128/2=64
x=64 degree
