Answer: 150 degrees

Reason: Vertically opposite angles are similar

(When two straight lines form an X when crossing over one another, an angle and the angle on the opposite side of the X are the same)

The measure of angle 8 is 150 degrees.

What are opposite angles?

Opposite angles are angles that are found opposite each other. They are formed when two lines intersect. The value of a pair of opposite angles is equal.

The value of the angle can be found as shown below:

It is given that angle 5 is equal to 150 degrees.

The image is also provided.

We can see that angles 5 and 8 are opposite angles.

We know that opposite angles have equal measures.

This means that the measure of angle 8 is the same as angle 5.

The measure of angle 5 is 150 degrees. Therefore, the measure of angle 8 is also 150 degrees.

We have found that the measure of angle 8 is the same as angle 5 which is 150 degrees since they are opposite angles.

Therefore, we have found that the measure of angle 8 is 150 degrees.
