Use the diagram to answer the following question.

If m∠4=(3x+7)°, and m∠5 = (9x−43)°, find the following:

x =

m∠4 =
º

m∠5 =
º

Answer 1

Answer:

Step-by-step explanation:

3x + 7 + 9x - 43 = 180

                    12x = 216

                      x = 18

m∠4 = 3(18) + 7 = 61°

m∠5 = 9(18) − 43 = 119°
