What type of graphs
if it is a bar graph look at the hights or the ranges
if it is a line graph look at how much it drops or how much it raises by
if it is just any kind of graph look at y and x axis how much does it skip
2, sin( θ )=6/12=1/2 => theta=30 degrees.
=> triangle is 30-60-90
3.
Cos(45)=sqrt(2)/2
=> x=10*sqrt(2)/2=5sqrt(2)
To do that you should put it in slope intercept form and then graph, you should already know how to do this.
