Try this, ! the measure of a vertex angle of an isosceles triangle is 120º, the length of a leg is 8cm. find the length of a diameter of the circle circumscribed about this triangle. what is the radius in centimeters?

16

Step-by-step explanation:

The correct answer is 16. I don't have the work for it, but I just had a class and got the answer. The other answer that has the green box around it is not actually the answer.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
