Answers:
sin(x) = 3/5
cos(y) = 3/5
They are both equal to the same value
Explanation:
Use the Pythagorean theorem to find the hypotenuse
a^2+b^2 = c^2
8^2+6^2 = c^2
100 = c^2
c^2 = 100
c = sqrt(100)
c = 10
The hypotenuse is 10 units long.
Now compute the sine of angle x.
sin(angle) = oppposite/hypotenuse
sin(x) = 6/10
sin(x) = 3/5
Also, find the cosine of angle y
cos(angle) = adjacent/hypotenuse
cos(y) = 6/10
cos(y) = 3/5
It turns out that sin(x) = cos(y) if and only if x+y = 90.
