Question

Solve for x and then find the measure of B

Answer 1

Answer:

x = 9      Angle B = 40 degrees

Step-by-step explanation:

Angles A and B are congruent, so the equation are the same

5x - 5 = 3x + 13

-3x       - 3x              Subtract 3x from both sides

2x - 5 = 13

    + 5   +5                Add 5 to both sides

2x = 18                      Divide both sides by 2

x = 9

Plug this into the equation for angle B

B = 3(9) + 13      Multiply

B = 27 + 13        Add

B = 40
