Angle: 60°(pi/3 Rad)

Complementary angle: 30°(pi/6 Rad)

Supplementary angle: 120° ( 2 pi/3 Rad)

30/120=.25

Method used to obtain:

Complementary angles are (90° - the angle): 90-x. Supplementary angles are (180°- the angle): 180-x. But, the Comp is only 25% of the Supp so multiply the Supp by 25% (divide by 4) and set them equal to each other and then solve for x.

90-x=(180-x)/4

4(90-x)=180-x

360-4x=180-x

180=3x

x=60

an angle that is 54 degrees less than 4 times its complement

43 degrees

Complementary angles sum to give 90 degrees. Therefore the complement to an 85 degree angle is a 5 degree angle.

The complement is (90 - the angle) or: how much you have to add to the angle to make 90 degrees.(90 - 72.354) = 17.646 degrees.

Suppose the angle is x degrees. Then (180 - x) = 4*(90 - x) 180 - x = 360 - 4x 3x = 180 so x = 60 degrees.

15 degrees.Though the problem uses geometric terminology, it's actually best done with algebra.Knowing that an angle and its complement add to 90, we can express the angle's complement as (90 - x).Similarly, since an angle with its supplement add to 180, we can express the supplement as (180 - x).Now we can put these together to0 create the basis for finding x.(90 - x) + (180 - x) = 240All that's left is to simplify step by step until we get our solution.90 - x + 180 - x = 240270 - 2x = 240-2x = -302x = 30x = 15And to verify, a 15-degree angle has a 75-degree complement and a 165-degree supplement. Sure enough, 75+165=240.
