The difference in the measures of two complementary angles is 12°.find the measures of the angles.
let the smaller no. be x
therefore bigger no. = x +12
complementary angle = 90
therefore the 2 angles are = x + x +12 = 90
2x + 12 = 90
2x = 90 - 12 = 78
2x = 78
therefore x = 78 / 2 = 39
therefore x + 12 = 39 + 12 = 51
therefore two angles are 39 and 51
hope it helped u............
