Answer:
sin(y)=15/17
cos(y)=8/17
tan(y)=15/8
Step-by-step explanation:
We know that sinФ=Opposite/Hypotenuse, cosФ=Adjacent/Hypotenuse, and tanФ=Opposite/Adjacent. We can remember this with the phrase SOH-CAH-TOA.
We know our angle is Y. The opposite side of Y is 15. The adjacent side of Y is 8. The hypothenuse is 17.
Now, we can plug the given information into the formulas and get the solutions.
If the expression is 'seven less than n', we are subtracting 'seven' from 'n'.
yes
y = 9
x = 1
1 = 9 - 8
