Step-by-step explanation:

sum of angles in a triangle is 180

(26x - 2) + 70 + 60 = 180

26x -2 = 180 - 70 - 60

26x - 2 = 50

26x = 52

x = 2

hope this helped

Step-by-step explanation: The interior angles of triangles will ALWAYS add up to 180 degrees. In this case 2 angles are already provided, 70 and 60, so adding those together (130) the remaining angle must be 50 (180-130=50). In 26x-2=50, x=2 is the only possible answer. (Feel free to ask any questions if you don't understand anything I said!)
