Question

What is the tangent ratio for angle b?

Answer 1

Tan = opposite side/adjacent side
So opposite side is 2 and
Adjacent side is 1
2/1

Answer 2

Hi there!

Tangent is a trigonometry ratio, and it is the value of the side opposite the angle over the side adjacent to the angle. 

The side that is opposite angle B is side CA which is equal to 2. 
The side that is adjacent to angle B is side CB which is equal to 1. 

Therefore, the tangent ratio for angle B is 2/1.
(The adjacent side cannot be side BA because it is the hypotenuse.)

Hope this helps!! :)
