If ABCD is a square then each angle has to be a 90 degree angle so angle A = 90 so 5x + 50 = 90 To simplify we need to subtract 50 from both sides 5x + 50 = 90 - 50 - 50 5x = 40 To simplify further we need to divide both sides by 5 5x/5 = 40/5 x = 8

Just a tip, if you have a square, ALL the angles will ALWAYS be 90 degree angles!
