We know that consecutive angles in a parallelogram are supplementary, as they are consecutive interior angles between parallel lines.
Then, if we add the measure of x° and the measure of 5x° we get 180°. Then, we can write this expression and solve for x:

Then, the angle x has a measure of 30° and the angle 5x has a measure of 5*30=150°.
Answer: a. 30°, 150°, 30°, 150°
Answer:
3b - 4
Step-by-step explanation:
The answer is <span>-6(m2 - 3m + 6)
</span>
-6m2 + 18m - 36 = - (6m2 - 18m + 36)
= - (6m2 - 6*3m + 6*6)
= -6(m2 - 3m +6)
