Answer:
option D
Step-by-step explanation:
take 39 degree as reference angle
using cos rule
cos 39 = adjacent / hypotenuse
0.77 = x / 7
x = 7*0.77
x = 5.39
x = 5.4
$116
The Simple Interest formula is i = prt. Here,
i = ($1,450)(0.04)(2 yr) = $116
x + 6
If you dont know the value of x you cant solve the problem fully
