Write the complex number in the form a + bi. 3(cos60° + i sin 60°)

​

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

i believe the correct answer is b.

i think the amount would be $140.62
