Use Figure 1 to evaluate each trigonometric function of angle A . The side adjacent to angle A has length 8 and the side opposit
jonny [76]

The trigonometric ratios are;

  • Sin A = 0.78
  • Cos A = 0.625
  • Tan A =  1.25
<h3>What are the trigonometric ratio?</h3>

The trigonometric ratios are sine, cosine and tangent. Now we have the hypotenuse of the triangle. Figure 1 has been shown in the image attached to this answer.

c = √8^2 + 10^2

c = 12.8

sin A = 10/12.8 = 0.78

Cos A = 8/12.8 = 0.625

Tan A = 10/8  = 1.25
