Use the image below to answer the following question:

what relationship do the ratios of sin x° and cos y° share?

the ratios are opposites (16 over 20 and negative 16 over 20)
the ratios are both identical (16 over 20 and 16 over 20)
the ratios are both negative (negative 16 over 20 and negative 16 over 20)
the ratios are reciprocals (16 over 20 and 20 over 16)

The ratios are both identical (16 over 20 and 16 over 20)

Step-by-step explanation:

we know that

In the right triangle of the figure

----> opposite side angle x divided by the hypotenuse

----> adjacent side angle y divided by the hypotenuse

therefore

Because  x and y are complementary angles

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
