What is the solution to this system of equations?
3x + y = 17
x + 2y = 49

A. It has no solution.

B. It has infinite solutions.

C. It has a single solution: x = 15, y = 17.

D. It has a single solution: x = -3, y = 26.

d) the triangle is a right triangle 60 squared +144 squared= 156 squared

step-by-step explanation:

156 squared is the hypothenuse

so 156= c
