The image shows a triangle with three letters. At the top of the triangle is the letter B with the equation: 5x+4 right next to it. At the bottom left corner of the triangle, is the letter A with the equation: 4x+14 right next to it. At the bottom right corner of the triangle, is the letter C with the equation: 6x-3 right next to it.

To find the measures of the angles in the triangle using the Triangle Angle Sum Theorem, which states that the sum of the angles in a triangle is always 180 degrees, we can start by setting up the equations based on the angles given.

Let:

  • Angle A = 4x+14
  • Angle B = 5x+4
  • Angle C = 6x3

According to the Triangle Angle Sum Theorem: Angle A+Angle B+Angle C=180 Substituting the expressions for each angle: (4x+14)+(5x+4)+(6x3)=180

Now, combine like terms: 4x+5x+6x+14+43=180 15x+15=180

Next, subtract 15 from both sides: 15x=165

Now, divide by 15: x=11

Now that we have the value of x, we can substitute it back into the expressions for each angle to find their measures.

  1. Calculate Angle A: A=4(11)+14=44+14=58

  2. Calculate Angle B: B=5(11)+4=55+4=59

  3. Calculate Angle C: C=6(11)3=663=63

The angles of the triangle are:

  • Angle A = 58
  • Angle B = 59
  • Angle C = 63

Thus, the measures of the angles for the triangle are: 59°, 58°, and 63°.
