The three little lines through the sides of the triangle mean all three sides are equal. Because all three sides are equal the three inside angles would aso be equal.


The three angles of a triangle need to equal 180, so we can divide 180 by 3 to find what each angle is:

180 / 3 = 60.


Now we can set the equation with x in it to equal 60:


7x +4 = 60

Subtract 4 from each side:

7x = 56

Divide each side by 7:

x = 56 / 7

x = 8
