Answer:
Angle A is 50 degree
Step-by-step explanation:
As we know, the measure of exterior angle is equal to the sum of opposite interior angles.
115 = 65 + angle A
115 - 65 = Angle A

Step-by-step explanation:
angle ACD+ACB=180°(linear pair)
115°+angle ACB=180°
angle ACB=180°-115°
Angle C=65°
angleA + angleB + angleC =180°(angle sum of triangle)
angleA + 65° + 65°=180°
angleA = 180°- 130°
angleA = 50°
