The formula for the light bend would be n1*sin i= n2 * sin r
If you use "sin (90-x)= cos x" principle, you can change the sin in the equation into
n1*sin i= n2 * sin r
n1 * cos a= n2 * cos b
n2/n1= cos a/ cos b
Assuming the n constant is the ratio of the glass compared to water then the answer would be: cos a/ cos b
A) 264 11/2 *48
B) 66 pounds of beef needed .25*264
C) 66 pounds
Step-by-step explanation:
in fraction it comes 36/121
and in decimal.it comes 0.3
It is the graph where the two lines intersect, when they intersect there is a point where they connect, and that is your answer
