Answer:
x = 17
Step-by-step explanation:
A triangle's sum is 180 degrees, hence
6x + 10 + x + 17 + 4x - 34 = 180.
11x + 10 + 17 - 34 = 180
11x - 7 = 180
11x = 187
hope this helps and is right!! p.s. i really need brainliest :)
x+17+4x-34+6x+10=180(sum of angles in a triangle is 180)
11x-7=180
11x=187
x=187/11
x=17
