To use the triangle angle sum theorem, we need to set up the equation:
5x + 4 + 4x + 14 + 6x + (-3) = 180
Combining like terms, we get:
15x + 15 = 180
Subtracting 15 from both sides:
15x = 165
Dividing both sides by 15:
x = 11
Now, we can substitute this value back into the expressions for the angles:
Angle 1 = 5(11) + 4 = 59
Angle 2 = 4(11) + 14 = 58
Angle 3 = 6(11) - 3 = 63
Therefore, the measures of the angles are 59, 58, and 63.
The correct answer is C) 59, 58, and 63.
