Angles in a triangle add up to 180 degrees.
Find all the angles in the triangles by using this info.

To use sin or cosine, you need a right triangle. Remember, cos(theta) = adj/hyp and sin(theta) = opp/hyp.
Solve for the side shared by both triangles first. From this you will get part of x and the line in the middle of the large triangle. Use this line to solve for the hypotenuse of the large triangle then use the hypotenuse to solve for the other part of x. Add both x's together to get your answer

Find the missing value
yawa3891 [41]
It is easier to write the equivalent ratios first, then use that information to find the missing values.

3. ratio: cars/trucks = 3/5, or trucks/cars = 5/3. Missing value: 6/3*5 = 10.

4. ratio: TVs/Computers = 2/7, or Computers/TVs = 7/2. Missing value: 21/7*2 = 6.

Consider a 7.5%, $145,000, 25-year mortgage loan with 1/2% origination fee, 3/4 of a point, $550 mortgage insurance fee, $360 do
salantis [7]
A) The payment on the loan will be 1071.54, so after 300 payments, you will have repaid $321,462.00

b) Fees deducted from the loan amount for reporting purposes are
• 1/2% origination fee ($725)
• 3/4 point ($1087.50)
• $550 mortgage insurance fee
for a total of $2362.50.
Thus the proceeds of the loan are $142,637.50 and the reportable APR is the interest rate corresponding to the above payment on this amount.
  Reportable APR: about 7.688%

c) The "real" APR would include the effect of the additional fees on the loan proceeds. The escrow amount is not a loan cost, so is not included. These additional fees reduce the proceeds by
  $360 +395 +663 +125 +75 = $1618
so the "real APR" is calculated on proceeds of $141,019.50.
  Real APR: about 7.819%

d) Payments on a 10-year loan of $145,000 are $1721.18 per month. That payment amount on proceeds of $141,019.50 correspond to an interest rate of ...
  Real APR with early payoff: about 8.137%

There are various ways the payoff can be early. This calculation assumes you decide from the start to make payments in the amount that will result in early payoff. You could also pay a "balloon" payment after 10 years. I have not seen a description of how this calculation is made. I've only seen wording that says the "real APR is different if the payoff is early."

____
Several caveats:
• the methods described in your text are the ones you should use for this
• the different value of the final payment has not been figured in any of these calculations
• Here, the fees are deducted from the nominal loan amount. In real life, you will often add the fees to the loan amount so the proceeds are the amount necessary to close the sale on the property. (In other words, you'd make the loan for 148,980.50 so the proceeds were 145,000.)
