If 0° < θ < 90°, is sin θ equal to cos (90° – θ), and for what reason? a) no, because angles measuring θ and 90° – θ are supplements. b) no, because angles measuring θ and 90° – θ are complements. c) yes, because angles measuring θ and 90° – θ are supplements. d) yes, because angles measuring θ and 90° – θ are complements.

Option D. Yes, because angles measuring  and  are complements

Step-by-step explanation:

we know that

Two angles are complementary if their sum is equal to degrees

and

If two angles are complementary, then the function sine of one angle is equal to the function cosine of the other angle

therefore

In this problem

so

 and -----> are complementary angles

hence

21

step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
