Answer:
(-3, 3)
Step-by-step explanation:
The equation is:
to clear for x, first we move the -36 to the right as a +36 (or you can also say that we add 36 to both sides):
dividing by 4:
taking the square root:
±
we add the ± because a square root has two solutions, a positive one, and a negative one.
Then we get:
± 3
The solutions are -3 and +3
which is represented in the option (-3, 3)
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 ~
