Gt 2 1 Point Use The Right Triangle Below To Solve A C B C С B 1 1 A Which Trig Function Should Be Used To Find Side A If You Know The Measure Of Angle E 2 Sine class=

Answer :

Answer:

cosine

Explanation:

c is the hypotenuse of the triangle and a is the adjacent side of the angle B.

On the other hand, the trigonometric functions sine, cosine, and tangent are equal to:

[tex]\begin{gathered} \sin (Angle)=\frac{\text{Opposite Side}}{Hypotenuse} \\ \cos (\text{Angle)}=\frac{Adjacent\text{ Side}}{Hypotenuse} \\ \tan (\text{Angle)}=\frac{Opposite\text{ Side}}{Adjacent\text{ Side}} \end{gathered}[/tex]

So, the trigonometric function that relates the angle B with its adjacent side a and the hypotenuse c is cosine.

Therefore, the answer is cosine.
