Question

Can someone help me I have two more other questions they are 15 points each I just posted them right now! Thanks so much

Answer 1

76˚

Explanation:

All angles of a triangle total up to 180˚ so we can make this equation:

x - 14 + 1/2x + 7 + 2x - 128 = 180

3.5x - 135 = 180

3.5x = 315

x = 90

Angle A is x - 14

90 - 14

76
