hello,
Let us assume, third angle of a triangle is y and two angle of a triangle are a and b respectivelly,
Teo angles are equal. Therefore a = b = x
Condition: Sum of three angles = 180
Given:
y = x + 18 ----------1
To satisfy thr condition of a triangle
x + x + y = 180
2x + x + 18 = 180
3x = 162
x = 54
and therefore, y = x + 18 = 54 + 18 = 72
Therefore, three angles of a triangle are 54, 54, 72.
