Question

Find the cos sin and tan of 28 degrees in terms of the variables x, y, and k.

Answer 1

`sin(28) = (y)/(k) , cos(28) = (x)/(k) , tan(28) = (y)/(x)`

Explanation:

For this problem, k is the hypotenuse, x is the side adjacent to 28, and y is the side opposite 28.

I would remember SOH CAH TOA.

S - Sine

O - Opposite

H - Hypotenuse

For this, it shows that the sine of the angle is opposite over hypotenuse. Therefore, y/k.

C - Cosine

A - Adjacent

H - Hypotenuse

For this, it shows that the cosine of the angle is adjacent over hypotenuse. Therefore, x/k

T - Tangent

O - Opposite

A - Adjacent

For this, it shows that the tangent of the angle is opposite over adjacent. Therefore, y/x
