<span>The tricky part of the law of sines is knowing when you are able to use it. Whether you can use the law of Sine's or not depends on what information you have or were given. In some cases the information you were given could make two different triangles. There are three times when you can use the law of sines. One example of when you can use it is when you have the length of a side and the measures of both the angles that that side is adjacent to. This is called angle side angle or asa for short. Another time when you can use the law of sines is when you are given the measures of two angles and a side that is outside the angles. This is called aas. Finally the last case where you can use the law of sines is when you have two side lengths and the measure of an angle. Math teachers refer to this one as ssa, I remember that this one is special. If you are given the measure of an angle and two sides you could have two different triangles.</span>
The answer to your question is 15.6
Answer:
That's just -6
Step-by-step explanation:
The 19 is smaller then the 25 so you gotta go back to the negatives, so do 25 - 19 but add a negative.
Answer:
Step-by-step explanation:
The coordinates of the given quadrilaterals are
The reflection in the line 
has the mapping,
We just have to swap the coordinates.
This implies that,
Therefore the correct answer is A.
