Lines c and d are intersected by line p. At the intersection of lines c and p, the bottom left angle is (3 x + 45) degrees. At the intersection of lines d and p, the uppercase left angle is 81 degrees.

What must be the value of x so that lines c and d are parallel lines cut by transversal p?

12
18
81
99

Answer 1

B

Explanation:

Answer 2

x=12

Explanation:

1.) 3x+45=81

2.) 3x+45-45=81-45

3.) 3x=36

4.) 36/3

5.)x=12

*On step 2 you subtract 45 on each side if it wasnt clear.
