Write the algebraic expression described. Recall that two angles are complimentary if their sum is 90 degrees. If one angle measures f degrees, express the measure of its compliment in terms of f degrees

-

90°-f measure

Step-by-step explanation:

If f is one angle it's complementary is 90°-f

Prove:- 90°-f+f°= 90°

Hope this helps you.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
