The Triangle Angle Sum Theorem states that the sum of the three interior angles of a triangle is always 180 degrees. Using this theorem and the values provided in the diagram, we can add the angles together:
5x + 4 + 4x + 14 + 6x - 3 = 180
15x + 15 = 180
15x = 165
x = 11
Now we can substitute x back into the equations to find the angles:
5(11) + 4 = 59°
4(11) + 14 = 58°
6(11) - 3 = 63°
Therefore, the angles of the triangle are 59°, 58°, and 63°.
Therefore, the correct answer is:
59°, 58°, and 63°.
