SAS and not similar

Step-by-step explanation:

For the first one, the two triangles are similar (SAS) because the ratio of the two sides is the same (3:5) and the angle in between them is the same.

For the second one, the two triangles are not similar because if we look at the lengths of the sides which is the only information we have of them, we can see that their ratios are not the same.

step-by-step explanation:

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
