Since we know that a triangle equals to 180 degrees, we should start by adding together the two known angles inside the triangle. To determine to measure of the unknown angle, be sure to use the total sum of 180 degrees. If two angles are given, add them together and then subtract from 180 degrees. If two angles are the same and unknown, subtract the known angle from 180 degrees and then divide by 2.

Answer:
A. (4,1)
Step-by-step explanation:
2x -5y = 3
x -3y = 1
Change the equation to isolate a variable so you can substitute it in the other one.
x = 1+3y so
2(1+3y) -5y = 3
2 + 6y -5y =3
2 + y = 3
y=1
Back to the easy equation we isolated
x = 1+3(1)
x= 4
(4,1) is a point where x=4 and y=1
