Answer:
t=p*34
Step-by-step explanation:
t=p*T, where T is the bill for the table Joe waited on, p is the percent tip and t is the tip left for the waiter
In this situation, the bill is 34, so lets plug that in
3.50 cups
6-2.25=4.75
4.75-1.25=3.50
.87 I think
I believe you have to evaluate the inverse tangent first then do the sine.
tan^-1 34/19 is about 1.06
sin 1.06 is about .87
