The answer is b island bike rentals $100 bicycle company $85. island bike rental goes up by $20 every day while bicycle company starts at $25 and goes up by $15 every day
SinA = 3/5
cosA = 4/5
cosB = 3/5
sinB = 4/5
sin(A+B) = sinAcosB + cosAsinB
= (3/5)(3/5) + (4/5)(4/5)
= 9/25 + 16/25
=(9+16)/25
=25/25
=1
therefore, the answer is B
