Using the unit circle to help, we must determine what value of theta (in radians) makes cosine -1.
On the unit circle, there is only place where cosine is -1, and that is at π.
Since it asks to find all solutions, we use the “+ 2kπ” to account for them. (Let me know if you need an explanation of why this works/what this means.)

Answers
The hypotenuse of the right triangle is 29 units.
The ratios are as follows:
sin x = 20 / 29
cos y = 20 / 29
What is a right angle triangle?Right angle triangle has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios. The sides can also be solved using Pythagoras theorem.
The hypotenuse side is the longest side of a right angle triangle.
Therefore,
c² = a² + b²
c = √20² + 21²
c = √400 + 441
c = √841
c = 29
hypotenuse = 29 units
sin x = opposite / hypotenuse = 20 / 29
cos y = adjacent/ hypotenuse = 20 / 29
