Answer:
The exterior angle is 95 degrees.
Explanation:
Statement Used : The exterior angle of a triangle is equal to the sum of the two opposite interior angles. ( see attached image )
The exterior angle is positioned at the question mark and the two opposite interior angles are ∠D and ∠E
Which means ? = ∠D + ∠E
We are given that ∠D = 45 and ∠E = 50
So , ? = 45 + 50 = 95°
