SR =sin (angle) = opposite leg/ hypotenuse

sin(52) = SR/ 7.6

SR = 7.6 x sin(52)

SR = 5.988 ( round answer as needed.)

QR = cos(angle) = adjacent leg / hypotenuse

Cos(52) = QR/ 7.6

QR = 7.6 x cos(52)

QR = 4.679. ( round answer as needed).

bezimeni [28]
It is a function because in a function the x's do not repeat. So since there are no two numbers in the x column that are the same, yes it is a function.

A bell rings every 1/6 hour. assuming it just rang,how many times will it ring in the next 2/3 hour?
Paraphin [41]

1 hr = 60 min

1/6 hr = (60/6) min = 10 min

so the bell rings every 10 min. Since 1 hr = 60 min, this means that 2/3 of that is 40 min. So the bell will ring 4 times (divide 40 over 4) in the next 2/3 of an hour, which is the same as saying "the bell will ring 4 times in the next 40 minutes"

Answer: 4 times
