Answer: B
Step-by-step explanation:
Since it is an equilateral triangle, each angle is equal to 60 degrees and all the sides are the same length
Finding x
since the sides are all the same 3x - 8 = 2x -1, so rearrange and solve for x
3x - 8 = 2x - 1
x - 8 = -1
x = 7
x = 7
Finding y
since each angle is equal to 60, 4y - 4 = 60, so rearrange and solve for y
4y - 4 = 60
4y = 64
y = 16
Final Answer
B - x = 7, y = 16
