Using trigonometric identities, it is found that the sine and the tangent of the angle are given as follows:
.
We use the following identity:
In this problem, the cosine is:
Hence the sine is found as follows:
Second quadrant, so the sine is positive, hence:
The tangent is given by the <u>sine divided by the cosine</u>, hence:
Hence:
