Answer:
The value of b nearest whole number is, 13.
Step-by-step explanation:
We know an and the side adjacent to it i.e, a=12.\
In a right triangle BCA ,
the <u>tangent(tan) </u>of an angle is the length of the opposite side divided by the length of the adjacent side.
i.e,
Substitute the value of a=12 and to solve for b in above expression:
we have the value of
then,
On simplify we get,
Therefore, the value of b nearest whole is, 13
