Use this applet to visualize the definition of complementary angles.
1. If one angle measures 42˚, then its complement will measure _____ degrees.
Its complement will measure 48 degrees[br][br]90 - 42 = 48
2. If an angle's measure is represented by x, then the algebraic expression we can write to represent its complement is _______
90 – x[br][br](notice: x + 90 – x = 90)
