suppose that a roof is built so that the angle at the peak and the lengths of the sides, which differ, are known. how would the width of the house be determined?

Using the Law of Cosines.  

As with many math problems, there are a number of ways this problem can be worked. Perhaps the most straightforward is to use the Law of Cosines to compute the side (c) opposite the given angle (C), given the sides (a, b) adjacent to that angle.

c² = a² + b² -2ab·cos(C)

Then the desired width of the house is ...

c = √(c²)

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
