Answer:
y = 7
Step-by-step explanation:
The triangle above is an equilateral triangle. An equilateral triangle have three equal sides. The angles are also congruent. Each angle is 60° in an equilateral triangle.
The angle C = 8y - 4
since each angle is 60°,
8y - 4 = 60
8y = 60 - 4
8y = 56
divide both side by 8
y = 56/8
y = 7
The x value can also be found in the same manner.
3x - 3 = 60
3x = 57
x = 57/3
x = 19
