Step-by-step explanation:
Answer:
x = 5 and z = 108
Step-by-step explanation:
We have two intersection lines and since z and 108 lie opposite each other, they are called vertical angles. By definition, vertical angles are congruent to each other, so that means z = 108.
Now, notice that z and 6x + 42 lie on the same line. A line has a measure of 180 degrees, which means that these two will add up to 180 (they are supplementary angles). Then we can write:
z + (6x + 42) = 180
We already know that z = 108, so plug that in and solve for x:
108 + (6x + 42) = 180
6x + 150 = 180
6x = 30
x = 5
Thus, x = 5 and z = 108.
