You should’ve put an attachment so I can be sure what I’m looking at. Because it’s not possible for isosceles triangles to have all equal angles. Isosceles triangles have 2 equal sides and angles. Equilateral triangles have 3 equal sides and angles.
But I’ll try to help you with this problem. Here are two cases.
One, the problem is actually an equilateral triangle and all sides are indeed equal. The angles in a triangle adds up to 180 degrees. So if all angles are equal, divide 180 by 3 and you get 60. So all angles would be 60 degrees and so should x.
Two, the triangle is isosceles, we will cross out the rest of sentence one after the comma. Since there are no given information about the triangle and I believe the random numbers below the question are the choices, I will teach you how to do this problem. It’s easy. So we already know that a triangle adds up to 180, now we will take 180 and subtract it by the two given and known angles. The remaining number will be what x is.
Hope this helped, good luck!
