Sine: sin(θ) =Opposite /Hypotenuse Now put in the values we know: sin(39°) = d / 30 And solve that equation! But how do we calculatesin(39°)... ? Use your calculator. Type in 39 and then use the "sin" key. That's easy!
... it takes theratio"opposite/hypotenuse" and gives us an angle. Example: Sine Function: sin(30°) =0.5 Inverse Sine Function: sin-1(0.5) =30° On the calculator press one of the following (depending on your brand of calculator): either '2ndF sin' or 'shift sin'. ...
there is no angle that has a sine greater than 1. The inverse sine or arcsin of 1.732 does not exist. That's what the calculator is saying.

sin(θ)=oppositehypotenusesin(16∘)=height11 To get the height by itself, we will multiply both sides of this equation by 11 to get the following: 11×sin(16∘)=height Making sure to use the degree mode on our calculator, we can calculate the sine of16∘to getsin...
When you use the sine key, you put in an angle and get out the sine of that angle. For instance, when you do sin(30) you are finding the sine of 30 degrees and the calculator says it's 0.5. When you use the inverse sine (shift-sine) you put in the value of the sine and th...
