2. Which equation could be used to find the length of line segment (NM)? Hint: Use Sin when given the hypotenuse. Use Tan when given a leg.

21

N

20

A. (21) Tan (20°) = line segment (NM)

B.(21) Sin (20°) = line segment (NM)

Diagram isnt given. However, a picture illustribg the possible scenarios has been attached to help.

KINDLY CHECK EXPLANATION

Step-by-step explanation:

Given the triangles A and B below :

Using trigonometric ratios :

If triangle A is given ;

Then ; MN will be obtained using the SIN relation :

Sin 20 = opposite (MN) / hypotenus (21)

If triangle B is given ;

Then ; MN will be obtained using the TAN relation :

Tan 20 = opposite (MN) / Adjacent (21)
