Soh cah toa is your best friend in trig

sin(x) = opposite/hypotenuse
cos(x) = adjacent/hypotenuse
tan(x) = opposite/adjacent

X is opposite from 43 degrees.
16 is the hypotenuse because it’s the longest side.

We need to use sin(x) because we’re given the opposite/hypotenuse ratio.

For sin(x) plug in the angle for x:

sin(43) = X/16
Multiply both sides by 16.

X = 16*sin(43)
You can plug it into your calculator.

I don't know how to do this. Any help?
Brut [27]

Answer:

cos 37=x/b (second one)

sin 37= a/b (third one)

tan 37=a/x (sixth one)

Step-by-step explanation:

Cos is defined by the adjacent side over the hypotenuse. Cos 37 would be x/b. Clearly, that is option 2. Sin is defined by opposite over hypotenuse. Sin 37 would be a/b. That is the 3rd option. Tan is defined by opposite over adjacent. Tan 37 would be a/x or the 6th option.
