25+80=105
180-105=75=a

y=90 because it’s a right triangle so

25+90=115
180-115=65=x

y=90
x=65
a=75

The measure of the three angles are 56, 28 , 192 degree

<h3>What is a Triangle ?</h3>

A triangle is a polygon with three sides , three vertices an three angles.

It is given to make system of equations

Let the measure of the first , second and third angle be x, y and z

the sum of the measures of the first two angles is 12 less than the measure of the third angle.

x +y = z -12 ----1

the measure of the first angle is twice as big as the measure of the second angle.

x = 2y

Now equation 1 will be

z - 3y = 12

x +y+z = 180

2y +y +z = 180

3y +z = 180 ----2

z - 3y = 12------3

On solving the system of equation 1, 2

2z = 192

z= 96 degree

3y = 180-96

y = 28

x = 56

Therefore the measure of the three angles area 56, 28 , 192 degree.

73. Suppose that you want to buy a house that costs $175,000. You can make a 10% down payment, and 1.2% of the house’s value is

Irina-Kira [14]

Answer:

total monthly payment is $973.03

Step-by-step explanation:

given data

costs = $175,000

down payment = 10%

house value paid = 1.2%

to find out

monthly payment for a 30 year i.e 360 months

solution

we consider here rate of interest for 30 year is 4.25% so monthly interst rate will be $\frac{0.0425}{12}$ = 0.00375

so We have present value Ap = 0.9 ( 175000) = $157500

and the monthly escrow payment is

monthly escrow payment = $\frac{1}{12}$ × 0.012 × 175000

monthly escrow payment = $175

so monthly payment formula is

monthly payment = $\frac{Ap*r}{1-(1+r)^{-n}}$ ..................1

here r is rate and n is time period

monthly payment = $\frac{157500*0.00375}{1-(1+0.00375)^{-360}}$

monthly payment = 798.03

so the payment to the loan is $798.03 each month

and Then the total monthly payment is = $798.03 + $175

total monthly payment is $973.03
