Use the image to answer the question.
A triangle a b c is shown with angle a measuring 4 x plus 14, angle b measuring 5 x plus 4, and angle c measuring 6 x minus 3.

To find the measure of the angles in the triangle, we can use the Triangle Angle Sum Theorem, which states that the sum of the angles in a triangle is always 180°.
Therefore, we can set up the equation:
(4x + 14) + (5x + 4) + (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 find the measure of each angle by substituting the value of x back into the expressions:
Angle a = 4x + 14 = 4(11) + 14 = 44 + 14 = 58°
Angle b = 5x + 4 = 5(11) + 4 = 55 + 4 = 59°
Angle c = 6x - 3 = 6(11) - 3 = 66 - 3 = 63°
Therefore, the measure of the angles for the triangle in the diagram is 58°, 59°, and 63°.
