Answer 1

To find the measures of the angles, set up the equation:

4x + 14 + 5x + 4 + 6x - 3 = 180
Combine like terms:
15x + 15 = 180
Subtract 15 from both sides:
15x = 165
Divide by 15:
x = 11

Now, substitute x back into each angle's expression:
Angle a: 4(11) + 14 = 59 degrees
Angle b: 5(11) + 4 = 59 degrees
Angle c: 6(11) - 3 = 63 degrees

Therefore, the measures of the angles are 59°, 59°, and 63°. So, the correct answer is:
59°, 59°, and 63°
