"one third" is not an event and so cannot have complement nor a probability.
Suppose the angle is x degrees. Its complement is 90-x So x is 2/3 of (90-x) 3x = 2*(90-x) = 180 - 2x 5x = 180 so that x = 36 degrees

You can calculate the angle Let X =angle in degrees The complement is 90 -x 1/3(90-X) = X 30 - X/3 = X 30 = 4X/3 X = 22.5 degrees
one-third of x is x/3
180-x= 2(90+x) - 60 180-x=180+2x - 60 -x=-60 x=60 Are you in my honors geometry class? The algebra is wrong. the third line should read -3x=-60 x=20 therefore the complement is 70o This agrees with the answer in the back of the book.

Suppose the angle is x. Then its complement is 90-x x - 50 = 90 - x or 2x = 140 so that x =70.
x/3
One Direction were third.
Third
Complementary angles sum to 90°. Supplementary angles sum to 180°. Given an angle x then the complement of x is 90 - x, and the supplement of x is 180 - x.
one half divided by 4 is 2. one third divided by x is 3
