The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is four times
REY [17]

Answer:

  (x, y, z) = (36°, 60°, 84°)

Step-by-step explanation:

Using the given variable definitions we can write the equations expressing the problem conditions.

  x + y + z = 180

  y + z = 4x

  z = y + 24

Substituting the second equation into the first, we have ...

  x +4x = 180

  x = 180/5 = 36

Substituting this value in the second equation and adding that to the third equation, we have ...

  (y +z) +(z) = (4·36) +(y +24)

  2z = 168 . . . . . . subtract y and collect terms

  z = 84

  y = 84 -24 = 60

The angle measures are ...

  (x, y, z) = (36°, 60°, 84°)

Suppose payments were made at the end of each month into an ordinary annuity earning interest at the rate of 4.5%/year compounde
valentina_108 [34]

Answer:

each payment = $214.20

Step-by-step explanation:

For ordinary annuity,

FVOA = PMT x [{(1+r/m)^(n*m)} - 1/(r/m)]

Here, FVOA = $50,000

year, n = 14

Since the interest will be paid monthly, m = 12

interest rate, r = 4.5% = 0.045

PMT = ?

Putting all the values into the ordinary annuity formula,

FVOA = PMT x [{(1+r/m)^(n*m)} - 1/(r/m)]

$50,000 = PMT x [{(1+0.045/12) ^ (14*12)} - 1/(0.045/12)]

or, $50,000 = PMT x [{(1+0.045/12) ^ (14*12)} - 1/(0.045/12)]

or, $50,000 = PMT x [(1.8754 - 1)/0.00375]

or, $50,000 = PMT x [(1.8754 - 1)/0.00375]

or, $50,000 = PMT x 233.4399

or, PMT = $50,000/233.4399

PMT = $214.19

or, monthly payment will be $214.20 (Nearest cent)
