Question

Write each trigonometric ratio as a fraction in simplest form. show all supporting work

Answer 1

Answer: $\frac{x}{20}$

Step-by-step explanation:

Sine uses the ratio,  $\frac{opposite}{hypotenuse}$ so we can plug in the information we know. since there is no current value for the opposite side of angle A, we can just use a variable to replace it.

$sinA=\frac{x}{20}$

You can't reduce this any further because there is an unknown variable.
