Step-by-step explanation:

the mistake was made when the value of cos 3 pi over 2 was calculated.

tan(A-B)= ?since tan=sin/cos

<u>sin</u><u>(</u><u>A-B</u><u>)</u> = <u>sinAcosB-cosAsinB</u>

cos(A-B) cosAcosB+sinAsinB

divide by cos on the RHS

tan(A-B)= <u>tanA-tanB</u>

1+tanAtanB

A snail moved 5 feet in 2 hours. How many feet will the snail move in 5 hours?
mamaluj [8]
The best way to do this is to set up a proportion

2       5
--- = ----
5       x

then cross multiply and divide

5 times 5=25/2=12.5

he would move 12.5 feet in 5 hours

I hope I've helped!
