A hexagon is an 6 sided shape. It has 6 angles therefore. here is a picture of a hexagon:
Just took the test and got the the correct answer *\(♡°▽°♡)/*
Look at the image down below!!
If it is a square, subtract (90+ whatever the other angle is) from 360. If it is a triangle than add 90 plus whatever other number the other angle is then subtract it from 180. A triangle is 180 degrees, and a square is 360 degrees.
Well first off if you have a negative sign in front of the seven, DO NOT have a plus sign because it will be confusing. So y-7=13? , You add 7 to 13 and = 20, so y= 20
