If your heart beats 72 times
a minute, how many times
will it beat in one day?

70*60=4200 in 1 hour.

4200*24=100,800 in 1 day.        

im alright what do you need

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
