Please help, i’m so confused

x = 20

Step-by-step explanation:

The triangle shown is an equilateral triangle.  An equilateral triangle has angles that are all the same.  Therefore, the expression 4x-20 equals the value of the angle, which is 60 degrees.  To find x, you just have to do some simple algebra.

4x - 20 = 60 set the expression equal to 60, that's what the angle equals

4x = 80 add 20 to both sides

x = 20 divide both sides by 4, and you get your answer

Hope this helps! :)
