8. ZK and ZL are complementary angles. If mZK = (3x + 3)" and mZL = (10x - 4)", find the measure of each angle.

The angles are 24 , 66

Step-by-step explanation:

If sum of two angles are 90, then they are complementary angles

m∠K + m∠L = 90

3x + 3 + 10x - 4 = 90

3x + 10x + 3 - 4 = 90      {Combine like terms}

13x - 1 = 90

Add 1 to both sides

13x = 90 + 1

13x = 91

Divide both sides by 13

x = 91/13

x = 7

m∠K = 3x + 3

        = 3*7 + 3

        = 21 + 3

       = 24

m∠L = 10x - 4

        = 10*7 - 4

       = 70 - 4

m∠L = 66

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.
