Answer:

A = 60

Explanation:

The exterior angle is equal to the sum of the opposite interior angles

119 = 3y+14 + 4y

Combine like terms

119 = 7y+14

Subtract 14 from each side

119-14 = 7y+14-14

105 = 7y

Divide each side by 7

105/7 = 7y/7

15 = y

We want to find Angle A

A = 4y

A = 4*15

A = 60
