Question

In an isosceles ∆ABC,AB=BC if A=angle 52°.What is the measures of angl e 3 .

Answer 1

if AB = BC
then
<A = < B = 52°

we know that, sum of angles in a triangle is 180°

so, <A + <B + <C = 180°

<C = 180 - 52 - 52 = 180 - 104 = 76°

<C = 76°

Hope you understand
any doubts, comment ;)(

Answer 2

solution

AB=BC

given AB=52

⇒ BC=52

AB+BC+AC=180

52+52+AC=180

104+AC=180

⇒ AC=180-104

⇒ AC=76°
