Answer:

The value of y is 63

Step-by-step explanation:

The sum of angles in a triangle is 180°.

The angles in the triangle are 54°, y°, y°

Sum of angles in the triangle = 54° + y° + y° = 54 + 2y°

To find y, equate the sum of the angles in the triangle to 180°

54° + 2y° = 180°

2y° = 180° - 54°

2y° = 126°

y = 126/2 = 63

You are purchasing a house 12 years from now. the estimated purchase price is $171,600.00. you want to make a 20% down payment.

Answer:
$238.33

Explanation:
Assume that the amount you need to save per month is x.

You will be saving monthly for 12 years. This means that the amount you will save after 12 years is:
amount saved after 12 years = 12 * 12 * x = 144x

Now, you need to save 20% of $171,600.00. We will first need to calculate this value.
20% of $171,600.00 = 0.2 * 171,600.00 = $34320

Now, to know your monthly savings, equate the total amount saved in 12 years with the amount that needs to be saved and solve for x as follows:
144x = 34320
x = 34320 / 144
x = 238.33

This means that, to meet your goal, you need to save $238.33 monthly for 12 years.

Hope this helps :)
