Complementary angles are 2 angles who add up to 90 degrees. Every one of the angles adds up to 90 degrees, so the assignment is asking you to find the missing number that makes the angles add up to 90.

Example: The first angle on your pager shows 45 and and a question mark. Ask yourself, what number + 45 = 90? The answer is 45. So, take the number of each angle they give you, and subtract it from 90. ( 90 - 45 ) and you have solved what the missing number ( ? ) is. Hope I helped!

Subtract the degrees shown by 90 since it is a right angle, which mean sit is at 90 degrees. so like for the 1st one, subtract 45 from 90. any questions?

I really need help!!!! Fast please
ANEK [815]

Answer:

approx 15%

Step-by-step explanation:

Allison puts $250 down and following that she makes 12 monthly payments of $124.49.  The sum of her payments (total cost) is thus $250 + (124.49/month)(12 months) = $1743.88

The total interest she pays is $1743.88 - ($124.49/month)(12 months), or

$250

We use the simple interest formula:  i = prt, where t is the number of years, and r is the interest rate as a decimal fraction:

$250 = $1599.99*r*1.

                                                                     $250

Solving this for r by division, we get r = --------------- = 0.1463, or approx 15%

                                                                  $1599.99
