The law of cosines is used for calculating one side of the triangle if the angle opposite to that side is given as well as the other sides. For this problem, we are given angle B. Therefore, the correct answer among the choices given is option 1 where a is equal to 5 and c is equal to 3.
The ratio of linear dimensions (side lengths) is the square root of the ratio of areas.
√1 : √4 = 1 : 2
The best choice is ...
B. 1:2
The triangles are not the same size so a dilation made the original one smaller and a translation moved it to map ABC to A'B'C'.
Answer:
B. (5,12,13)
Step-by-step explanation:
The only answer with two side lengths that are greater than the largest side length.
