Question

Use the image below to answer the following question. Find the value of sin x° and cos y°. What relationship do the ratios of sin x° and cos y° share? A right triangle is shown with one leg measuring 4 and another leg measuring 3. The angle across from the leg measuring 3 is marked x degrees, and the angle across from the leg measuring 4 is marked y degrees.

Answer 1

Sin=opposite side/hypotenuse

So let's first find the hypotenuse using pythagoras theorem 4²+3²=H² so H=5

Sin x=3/5

Cos=adjacent side/hypotenuse

Cos y=3/5

So the relationship is that both are the same value, hope it helps cheers!
