Not sure why such an old question is showing up on my feed...
Anyway, let

and

. Then we want to find the exact value of

.
Use the angle difference identity:

and right away we find

. By the Pythagorean theorem, we also find

. (Actually, this could potentially be negative, but let's assume all angles are in the first quadrant for convenience.)
Meanwhile, if

, then (by Pythagorean theorem)

, so

. And from this,

.
So,
<u>Let's solve this problem step-by-step</u>:

<u>Thus v = 14</u>
<u />
<u>Answer: v= 14</u>
<u></u>
Hope that helps!
