In the diagram, how many angles are alternate exterior angles with angle 5?
strojnjashka [21]

Answer:

One.

Explanation:

The attached figure shows the diagram of the given question.

We need to find how many angles are alternate exterior angles with angle 5?

Exterior angle = Angle that is made outside of the shape

Alternate angle = an angle opposite of a transversal line of another angle.

From the figure, 8, 7, 9, 10, 12, and 11 are the angles that are on the same transversal. 8, 7, 9, 10, and 12 are just exterior. It means that 11 is the alternate exterior of angle 5. So, only one angle is alternate exterior angles with angle 5.
