Tangent, Sine and Cosine Ratios

Find Cos(A) as a decimal rounded the the nearest ten-thousandth.

If you are given the opposite side and hypotenuse, which trig function should you use?

If you are given the two sides that are not the hypotenuse, which trig function should you use?

Given the following triangle, use the values x and y to determine the following: $$\sin\theta$$ ​ (a)   ; $$\cos\theta$$ ​ (b)   ; $$\tan\theta$$ ​ (c)  

sin A = ​​ (a)   ​

cos A = ​​ (b)  

tan A = ​ (c)  

sin X = ​ (a)  

cos X = ​ (b)  

tan X = ​ (c)  

What is the sine of the 48 degree angle?

sin J = ​ (a)  

cos J = ​ (b)  

tan J = ​ (c)
