I need help solving this because my teacher didn't help much

X=60°

Step-by-step explanation:

Hello Friend!

  Here's a couple things to help you out:)

Okay, now that we know that information, we can solve the problem. We know all the angles combined equal 180°. Since three tick marks are present, all the angles are equal. So, this is what we get. X+X+X=180°. Let's make this easier to see. Since the X values are the same,  X+X+X is the same as 3x. So, what are three X variables, which are the same, that equal 180? (3x=180). If we divided, then we find x=60°.

Allow me to let you in on a secret. This type of triangle is called a equilateral triangle. In a equilateral triangle, all the angles will always be 60°. I hope this helps. If you are still confused, let me know!
