Question

Please, help me. I don’t think this problem makes sense.

Answer 1

Answer: m<BCD = 130 degrees

9x - 5 = 4x + 5 + 65

simplify

9x - 5 = 4x + 70

add 5 to both sides

9x = 4x + 75

subtract 4x from both sides

5x = 75

divide both sides by 5

x = 15

substitute 15 for x

9(15) - 5

135 - 5

130

Therefore, m<BCD = 130 degrees
