Question

Identify the correct trigonometry formula to use to solve for x.

Answer 1

Answer:

sin(62)=18/x

Step-by-step explanation: sine = opp/hyp

Answer 2

Answer: Third option.

Step-by-step explanation:

Given the right triangle in the figure attached, you know that, for the known angle of 62 degrees, the lenght of the opposite side is 18 and the hypotenuse is "x"

Therefore, you need to remember the following identity:

$sin\alpha=\frac{opposite}{hypotenuse}$

Then, having that:

$\alpha=62\°\\opposite=18\\hypotenuse=x$

 You need to substitute these values into  $sin\alpha=\frac{opposite}{hypotenuse}$, then  you get that the correct trigonometry formula to use to solve for "x" is:

 $sin(62\°)=\frac{18}{x}$
