HERE'S UR ANSWER

AB=AC .......(given)
angle A = 36°
Therefore, by icosceles triangle theorem
( in a triangle, if two sides are congruent ...angles opposite to them are also congruent )
therefore....
angle A = angle C = 36°

HOPE IT HELPS.....

PLS MARK IT AS BRAINLIEST....❤❤❤

Hey Chika ❤

Here's ur answer-

We know that,

AB = AC
and, angle A = 36°

Property of Isosceles ∆ :
 \underline{two \: sides \: are \: equal}
 \underline{and \: corresponding \: angles \: to \: these \: sides \: are \: equal}
So, from above we get to Know that
angle ABC = angle BCA

we also know that,
sum of all angles of a ∆ is 180°.

So, let the angles be 'x
 = >  36 + x + x = 180 \\  =  > 2x = 180 - 36 \\  =  > 2x = 144 \\  =  > x = 144 \div 2 = 72
Hence, angle C = 72.

Hope it helps ✔
