find the exact value of sin(arctan( explain full reasoning in detail, .

Step-by-step explanation:

To solve this, all we need to do is draw a triangle.  

From the we can deduce that

From that, we can draw our triangle as we know that tan(x) is the opposite side over the adjacent side. Attached is that triangle. Through the Pythagorean Theorem, we can find that the hypotenuse of this right triangle is  

Now all we need to do is take the sin of this triangle, which is the opposite side over the hypotenuse

This gives us the value of which is our answer.

linear pair postulates

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
