1. Write out an equation to solve this. 2x + 7x - 9 = 90 degrees 2. Add 2x to 7x 9x - 9 = 90 degrees 3. Add 9 to both sides of the equal sign 9x = 99 degrees 4. Divide 9x by 9 to get x x = 11 degrees
If all the angles add up to 90 degrees then you can set the equation 7x-9*2x=90 Simplify 9x-9=90 Plus 9 both sides 9x=99 Divide by 9 on both sides X=11
