Well, 35/3 is simple, but 3 doesnt do into 35 so you might have gotten a long number, not big. But the answer is 11.66... or 11.6 repeating.
A triangle has angles that add up to 180 degrees.
4x - 13 + 15 + x + 18 = 180....combine like terms
5x + 20 = 180
5x = 180 - 20
5x = 160
x = 160/5
x = 32
< A = 4x - 13
< A = 4(32) - 13
< A = 115
< C = x + 18
< C = 32 + 18
< C = 50
180 degrees - 25 degrees =
A: 155 degrees
*note: 180 degrees total in a triangle
