#1 is wrong. Tangent will always be the two legs. It is opposite over adjacent. Thus, the answer would be 20/21.
#2-#4 look all correct but make sure that you write it to the ten thousands (including zeroes).
Okay, so onto number 5 and 6.
On number 5, you are trying to find the hypotenuse. The angle measure is what you must now use as your reference point. Using Tangent would not be right for this. Instead, you are given the adjacent and you need to figure out the hypotenuse so this would use cosine.
You can find the value by taking the cos(26)=17/hyp. This would be x = 17/cos(26)
This is about 18.9142.
#6 would be just as easy.
You will be using tangent for this one and tangent is opp/adj so its x/18=tan(39).
See if you can figure that one out. Also, make sure to be in degrees mode on the calculator
