I cant seem to figure this out at all i only know exteriors to a degree

Explanation:

There are two methods you could use. The first method involves the remote interior angle theorem. This says the remote interior angles (the two y angles) add to the exterior angle (130)

y+y = 130

2y = 130

y = 130/2

y = 65

Or we could find the interior angle that is adjacent to the 130 degree angle. This is 180-130 = 50 degrees. So this is the top interior angle of the triangle. For any triangle, the three interior angles always add to 180

angle1+angle2+angle3 = 180

y+y+50 = 180

2y+50 = 180

2y = 180-50

2y = 130 ... from here on out, the steps are the same as above

y = 130/2

y = 65

So this helps show how the remote interior angle theorem is set up

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
