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

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.

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )

good luck on your studies! : )
