Question

Using the following triangle, what is the tangent of angle B?

	A.
	B.
	C.
	D.

 

Find angle A in the following triangle.

	A.	50.67°
	B.	49.23°
	C.	48.19°
	D.	51.89°

 

Answer 1

1)

tan B = Opposite side/ Adjacent side

Here opposite side of B is b and adjacent side B is a 

tanB = b/a

Option B is correct .

 

 

Answer 2

2)

cos A = Adjacent side/ hypotenuse

Here adjacent side of A is 2 and hypotenuse of  A is 3

cos A =2/3

        =0.667

  A =   48.19                  

Option C is correct .
