On which triangle can the law of cosines be used to find the length of an unknown side?

Law of cosines: a2 = b2 + c2 – 2bccos(A)

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

total of apples - take away four

6-4 = 2

answer is 2 apples

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
