Which basic geometric term can be called "half of a line"? a. ray b. vertex c. segment d. angle

 A. Ray

Step-by-step explanation:

A ray is a part of a line that starts at a fixed point and goes towards in a particular direction to infinity where as a line has no endpoints such that it goes towards infinity from both the sides.

The point where the ray begins is known as its endpoint.

Similarly as a line, ray passes through infinite points on its way in a particular direction .

Thus, the basic geometric term can be called "half of a line" is ray.

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510
