What is the definition of ray in geometry?

A ray is a figure in geometry that starts at an endpoint

and continues forever going in one unique direction.

Unlike a line, a ray starts at a specific point and goes on.

To represent a ray, we use a small arrow at the top.

The arrow  (symbol) must always go to the right.

However, rays can go in any direction.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
