Solve the equation 1/30 + 1/45 = 1/x
where x is the required time
multiply thru by 90x:-
3x + 2x = 90
x = 90 / 5 = 18
answer 18 minutes
Since the measure of an angle is 12 degrees less than the measure of its supplement, then x=180-x-12 or 2x=168 or x=84 and 180-x=96. Step 4. ANSWER: The angle is 84 degrees and its supplementary angle is 96 degrees.
