Question

How do I find the values of x and y? Plus, how do I write my answer in simplest form. IMG_5801.jpg

Answer 1

Are you familiar with sine, cosine, and tangent?

Answer 2

Yes... but I don’t know how to use those formulas

Answer 3

Do you remember what they equal?

Answer 4

90 degrees?

Answer 5

No...

\(\sf sine=\dfrac{opposite}{hypotenuse}\)

\(\sf cosine=\dfrac{adjacent}{hypotenuse}\)

\(\sf tangent=\dfrac{opposite}{adjacent}\)

So which one can you use to calculate the sides?

Answer 9

Answer 10

probably tangent?

Answer 11

No, tangent is opposite over adjacent, that's the only one we can't use because we have two unknowns(x and y).

Answer 12

We know the hypotenuse and the angle.
