Answer:
a) x = 9
b) m∠BCD = 33°
c) use the fact that corresponding angles are congruent
Explanation:
a) Corresponding angle have the same measure, so ...
3x +6 = x +24
2x = 18 . . . . . . . . . . subtract (x+6) from both sides
x = 9 . . . . . . . . . . . . divide by 2
__
b) 3x+6 = 3(9) +6 = 27 +6 = 33 = m∠BCD
__
c) Use the relationship between corresponding angles. Solve the resulting equation.
