MCQ
If an angle is $28^\circ $ less than its complement, find its measure.
- ✓$31^\circ$
- B$131^\circ$
- C$28^\circ$
- D$32^\circ$
Two angles are complementary when they add upto form $90$ degrees.
If one angle $= x$
complemen of angle $= 90 - x$
Hence $x = 90 - x -28 ($given$)$
$2x = 90 - 28$
$2x = 62$
$\text{x}=\frac{62}{2}=31$
$= 31$
Hence angle is $31$ and its complementis $59$
