The arcs in the corners of the triangle mean that all 3 angles are the same.

Because the 3 angles are all the same this means that all 3 sides are also the same.


To solve for X, we can set 2 of the equations to equal each other and solve for x:


6x-3 = 3x +6

Add 3 to each side:

6x = 3x +9

Subtract 3x from each side:

3x = 9

Divide both sides by 3:

x = 9/3

X = 3


And if you replace x with 3 in each of the equations, they all equal 15.
