If the sine if 4/5, then the side opposite is 4 and the hypotenuse is 5. This means it's the 3, 4, 5 right triangle (or similar, such as 6, 8, 10).
cos = 3/5
tan = 4/3
cot = 3/4
sec = 5/3
csc = 5/4
Answer:
Reflection across y=0
Step-by-step explanation:
The Y axis splits the octagon in half, so if it was reflected it would be mapped onto itself.
You can tell if a graph represents a proportional relationship by identifying the y-intercept, or the point of the line that crosses the y-axis.
If the y-intercept is 0, then the relationship is proportional. This is called a direct relationship.
If the y-intercept is anything other than 0, then the relationship is not proportional. This is called an indirect relationship.
