Hi, We have a isosceles triangle.
Then,
There is two angles = (2x +2)°
As the sum of angles = 180° To the any triangle.
Then we wiil stay with:
(2x+2)° + (2x+2)° +(3x+1)° = 180°
Canceling °
2x+2+2x+2+3x+1=180
7x +5 = 180
7x = 180-5
7x = 175
Passing 7 dividing 175
x = 175/7
x = 25
This would be your answer!
