Answer:

Explanation:

uhmm 4x +27 ? 4 times 27? what number is that supposed to be

let me try

4x + 27 + 4x + 27 + 4x + 27 (equilateral means all sides r the same length so 3 times cuz 3 angles in triangle)

12x + 81 = 27 (ok its prob not 4x +27 since x would be a negative number but just change 27 to the number it actually is)

12x = -54

x = -4.5

there enjoy it should be right if the numbers u gave me r correct
