Well I'm not positive that this is right, but I'll have to say x= 5.0.
Total degrees of the triangle is 180
Since A is shown as the same size as C 73 + 73 =146 Degrees
180 - 146 = 34 missing degrees
6 * 5.0 + 4 = 34

x = 5

The triangle is an isosceles triangle. Therefore, the base angles are equal.

  • 73 = 8y - 7

8y = 73 + 7

8y = 80

y = 80 / 8

y = 10

Sum of angle in a triangle = 180°

∠A + ∠B + ∠C = 180°

73 + (6x + 4) + (8y - 7)   = 180

73 + 6x + 4 + 73  = 180

150 + 6x = 180

6x = 180 - 150

6x = 30

x = 30 / 6

x = 5
