The degree measure of an angle in a right triangle is x, and sin x = 1/3 . Which of these expressions are also equal to 1/3 ? Select all that apply. A) cos(x) b) cos(x - 45°) c) cos(45° - x) d) cos (60° - x ) e) cos(90° - x)

EXPLAIN

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

Given that,

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

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).

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

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
