### c.
Explanation
## Step 1: Finding the cosine value### Since
and
is in quadrant 4, we know that
, where
and
. In quadrant 4,
is positive. We can use the Pythagorean theorem (
) to find
.
. Thus,
.## Step 2: Calculating the tangent value### Now, we can find
using the identity
. Substituting the values, we get
.
