Answer:x=4
Step-by-step explanation:
Answer:
x = 4
Since it's a equilateral triangle, all sides are equal
So you can do the equation 3x - 1 = 11
You then add 1 on both sides, leaving the equation as 3x = 12
You divide both sides by 3, which leaves you with x = 4
18+62=80x
12+18=30x
x=80÷30=2
x>2
It is B i think
