The given expression is
We need an expression Which represents the same solution as the given expression.
It can be written as
Since is equivalent to given equation, therefore this equation represents the same solution as the given expression.
Hence, option B is correct.
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°
