Can someone help to get a better understanding of how to solve this questions and others like this?
Since one angle is 50°, then x = [ 180 - 50 ] / 2 = 130 / 2 = 65°
Since two angles = x, then these angles are equal
The triangle is
(a) acute - all angle are < 90°
(b) isosceles - two angles are equal, therefore the two sides opposite them are equal
