Answer:

e) cos(90° - x)

Step-by-step explanation:

we know that

If two angles are complementary, the cofunction identities state that the sine of one equals the cosine of the other and vice versa

The complementary angle of angle x is equal to (90-x) degrees

therefore

[tex]sin(x^o)=cos(90-x)^o[/tex]

The expression that should be equivalent to one-third is cos(90° - x).

Given that,

  • The degree measure of an angle in a right triangle is x.
  • And sin x = one-third.

Based on the above information, the following information should be considered:

  • In the case when the two angles are considered complementary so the co-function identified and stated that sine of one should be equivalent to the cosine of the other.

Based on this, the complementary angle of angle x should be equivalent to (90-x) degrees

Therefore we can conclude that the expression that should be equivalent to one-third is cos(90° - x).
