Pls help me with this question

x = 80 degrees

angle CBD and EFB are supplementary meaning they add up to 180 degrees, and given that angle CBD is 100 we would need to find the missing angle which would add up to 180 degrees.

So we would set up an equation of

X + 100 = 180

-100     -100

x = 80

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.
