Answer:
∠ 1 = 70°, ∠ 2 = 140
Step-by-step explanation:
110° and the adjacent angle inside the triangle are supplementary, then
angle = 180° - 110° = 70°
Since 2 sides of the triangle are congruent, then the triangle is isosceles
Thus the 2 base angles are congruent, then
∠ 1 = 70°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 2 is an exterior angle of the triangle, thus
∠ 2 = 70° + 70° = 140°
