Question

Set up an equation that can be used to solve the variable.

Answer 1

So sin in math means:

In a right angled triangle, the sine of an angle is: The length of the side opposite the angle divided by the length of the hypotenuse. The abbreviation is sin.

Con in math means:

In a right angled triangle, the cosine of an angle is: The length of the adjacent side divided by the length of the hypotenuse. The abbreviation is cos. cos(θ) = adjacent / hypotenuse.

in this case it has to be a sin. So its either A, or B.

Answer 2

(a)

Explanation:

Sin (37) = x/10.3

using trigonometric identity (Sin θ = AC/AB)
