Answer:

payment: $413.93
total repaid: $74,507.40
interest: $22,507.40

Step-by-step explanation:

(a) The monthly payment A on principal P at monthly rate r for n months can be computed using ...

A = Pr/(1 -(1+r)^-n)

For P=$52000, r = .051/12 = 0.00425, n = 12*15 = 180, the payment is ...

A = $52000·0.00425/(1 -1.00425^-180) ≈ $413.93

(b) The total of 180 payments is ...

180 · $413.93 = $74,507.40

(c) The difference from the principal is the interest paid:

$74,507.40 -52,000 = $22,507.40

The ratio of the measures of the angles in a triangle is 2:9:4 what is the measure of the largest angle ?

FrozenT [24]

You need to add all of these values together. This is 2 + 9 + 4 which gives 15

There are 180° in a triangle. Divide this by 15.

180/15 = 12

Then multiply this by the largest in the ratio; which is 9.

This is 12 x 9 which = 108°.

The largest angle is therefore 108°.

For reference, the ratio in degrees would look like this:

24:108:48, which adds up to 180°.
