Answer:

1. x = 68°

2. x = 72°

Step-by-step 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°
