MCQ
Find the complement of an angle whose measure is $3x - 8^\circ .$
- A$3x - 98^\circ $
- B$82^\circ - 3x$
- ✓$98^\circ - 3x$
- D$3x - 82^\circ $
✓
Answer
Correct option: C.
$98^\circ - 3x$
Complement of an angle $A = 90^\circ - A$
So, complement of angle
$3x - 8^\circ = 90^\circ - (3x - 8^\circ )$
$= 98^\circ - 3x$
