No invested $150 at 8.31% simple interest. what is the total amount of money after 3 years?

$187.395

Step-by-step explanation:

lets use the formula I=PRT

where I=interest

P=principal

R=rate

t=time

so the principal here is 150

we can get the rate by doing: 8.31/100

0.0831=rate

time=3

so

i=150*0.0831*3

i=37.395

to find the Total we need to add our interest to our principal:

37.395+150=187.395

Total=187.395

(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

60%
