N is 7.5 because prq is 3x the size of abc
Answer:
csc(x) = 
Step-by-step explanation:
sinx + cos^2(x)/sin(x) = sin(x) + (1-sin^2(x))/sin(x) = 1/sin(x) = csc(x)
csc(x) = 
4/5n – 1/5 = 2/5n
Add 1/5 to both sides
4/5n = 2/5n + 1/5
Subtract 2/5n from both sides
2/5n = 1/5
Divide both sides by 2/5
n = 1/2
