Hello there!
Pentagon = 5 sides.
For regular pentagon: 360/5 = 72. 180 - 72 = 108 degrees at each interior.
I hope this helps.
1 times 89 equals 89 or 89 times 1 equals 89
Answer: x = 8.4
Work: So, the goal of this equation is to get x by itself, and the first thing we need to do is get 22 out of that current side. To do that, we are going to add 22 on both sides, cancelling it on the side it's currently on. So, the new equation is 5x = 42. Now, we need to divide 5 on both sides, and like I said, I'll cancel on the side it's currently on. So, the answer is x = 8.4
