Here's the solution ~
Let's find the measure of hypotenuse first, by using Pythagoras theorem ;





Now, let's find the asked values ~



For Cos y :



As we can see that both sin x and Cos y have equal values, therefore The required relationships is equality.
I.e Sin x = Cos y
Hope it helps ~
Multiply the numbers
2(2/3)
2/1(2/3)= 4/3 = 1 1/3
I think it’s 25....Yeah I’m pretty sure it’s 25
