Answer:

45°

Explanation:

When 2 lines intersect at a point, opposite angles are congruent. Angles 8 and 9 are opposite angles, so these are called vertical angles.

If angle <9 is 45 degrees, then <8 is also 45 degrees.

Hope this helps! :)

Answer: 45

vertical angle theorem says that when you have intersecting lines, the angles across are equal
