What is the value of x? enter your answer in the box. x =

the answer is x = 8

explanation:

because all of the sides of this triangle are equal all of the angles have to be equal as well. We also know that all triangles must have angles that equal 180 degrees. since all the angles are the same we know that all of the angles are 60 degrees because 60 + 60 + 60 = 180.

so set up an equation: 7x + 4 = 60

subtract 4 from both sides: 7x = 56

divide both sides by 7: x = 8
