Find the value of x.
and find the value of y.

the unknown side is 12, and the angle y is 67.4°

Step-by-step explanation:

this is a right triangle with side 5 and hypotenuse 13.  By the Pythagorean Theorem, 13² = 5² + opp², where "opp" is the side opposite Angle y.

Then 169 = 25 + opp² and so opp = √144 = 12.

Now to find the angle y:  

              5

cos y = = 1.176 radians

              13

Converting 1.176 radians to degrees, we get

1.176    180°

* = 67.4°

$450.00 for 6 weeks

or

$300

step-by-step explanation:

$200.00 for first week $50.00 x5 equals $250 plus $200 equals $450.00 for six weeks.

$200 for first week

$200 x 0.10 = $20

$20 x 5 = $100

$200 + $100 = $300
