an angle is 12° less than twice its complement.Finds its angle

Sagot :

Angle's complement: x
Angle: 2x - 12   (12 less than twice its complement)
Sum of measure of complementary angle: 90°

Equation:

x + 2x - 12 = 90
3x - 12 = 90
3x = 90 + 12
3x = 102
3x/3 = 102/3
x = 34°   the angle's complement, smaller angle

For the angle, substitute 34 for x:
Angle = 2x - 12     (12 less than than twice the angle's complement )
          = 2 (34) - 12
          = 68 - 12
          = 56°

Answer:  The angle is 56°.

Check:
Angle + Angle's Complement = 90°
56° + 34° = 90°
90° = 90°  √


66 degrees.. not quite sure
