Answer:
X=60°
Step-by-step explanation:
Hello Friend!
Here's a couple things to help you out:)
- If you add up all the angles on any triangle, you will find they equal 180°.
- Second, the intersecting lines you see are called tick marks. They tell you that the sides are equal. This also means the angles are equal.
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!
