Answer:
1. x = 68°
2. x = 72°
Explanation:
1. the sides are 21 that's mean they're equal.. they're Isosceles triangle.. also in the in isosceles triangle the base angles are equal
the sum of the interior angles in a triangle is 180°
so base angles are: 180 - 44 = 136
to find a base angle or x: 136 ÷ 2 = 68
so x = 68°
2. the legs are equal, so the base angles also are equal.
the measure of third angle = the sum of all angles - the sum of two angles
so to find x:
180 - (54 + 54) = 72
so x = 72°
