The best way to answer this would be making a graph
For 1 sign it costs 54.50 and he makes 15
For 2 signs it costs 59 and he makes 30
For 3 signs it costs 63.50 and he makes 45
For 4 signs it costs 68 and he makes 60
For 5 signs it costs 72.50 and he makes 75
This means that after 5 signs Larry will be making profit
Answer:
Sin B = 5/13
Cos B = 12/13
tan A = 12/5
Step-by-step explanation:
Sin B = opposite side/ hypotenuse
Cos B = adjacent side / hypotenuse
= 12/13
tan A = opposite side /adjacent side
= 12/5
