If A represents an angle, its complement is 90-A.
If m<1 = 36, then its complement is 90-36 (degrees), or 54 (degrees).
X = 5!
4x+1=2x+11
-1 -1 (Subtract 1 from both sides)
4x =2x+10
-2x -2x (Subtract 2x from both sides)
2x = 10
—— ——
2x 2x (Divide both sides by 2x)
X = 5
-2x + 11 =31
-2x =31 - 11
-2x = 20
X = 20/2
X = 10
