The answer is 4

Step-by-step explanation:

because all of the angles need to add up to 180 so 17 x 4 is 68 and 68 - 8 = 60 and 60 x 3 = 180 so the answer would be 4

Answer:

4

Step-by-step explanation:

Since all the sides are congruent, so is the angles and in a triangle all angles add up to 180. To find the angle of one of them divide 180 by 3 which is 60.

Then put the equation equal to 60

17x - 8 = 60

17x = 68

x = 4
