GEOMETRY 4


If x-150 and x + 350 are complementary angles, find the value of x.

solution

Complementary angles add up to 900.

so,  x-150 + x + 350 = 900.

 x + x + 350 - 150 = 900.

 2x + 200 = 900.

  2x = 900 -  200

  2x = 700

  2x = 7035
  2       2

Hence x = 35

TRY THIS...............


 If 3x - 420 and 2x + 670 are complementary angles, find the value of x.
