Question

Find the value of x in each figure to the nearest tenth

Answer 1

\[\sin(x)=\frac{opposite}{hypotenuse} \\ \\ \sin(51)=\frac{x}{10}\]
Solve for x

Answer 2

@.Sam. I got 0.7771459 I'm pretty sure I did something wrong but I'm not sure what.

Answer 3

That's the correct value for the Sin of 51 degrees. However, if you look at what @.Sam. wrote, that value is equal to \(x/10\), not \(x\) itself. Solve\[\sin 51^\circ = 0.7771459 = \frac{x}{10}\] for \(x\) and what do you get?

Answer 4

Well. I don't actually know how to solve it...
