The answer is C because YZ and ZX are the legs while XY is the hypotenuse. A common way to determine the legs is to see which ones aren't the hypotenuse.

One leg of a 45 - 45 - 90 triangle measures 10 inches. What is the length of the hypotenuse

djyliett [7]

Answer:

Therefore the length of the hypotenuse is 14.14 inches.

Step-by-step explanation:

Given:

The Triangle is of 45 -45 - 90

Length of one leg = 10 inches

To Find:

Length of the hypotenuse = ?

Solution:

The Triangle is of 45 -45 - 90 ..................Given

So For 45 - 45 - 90 Both the Legs of Triangle is SAME

i.e Longer leg = Shorter leg = 10 inches

Now in Right angle Triangle By Pythagoras Theorem we have

$(\textrm{Hypotenuse})^{2} = (\textrm{Shorter leg})^{2}+(\textrm{Longer leg})^{2}$

On substituting the values we get

$Hypotenuse^{2}= 10^{2}+ 10^{2} \\\\Hypotenuse^{2}=200\\Square\ Rooting\ we\ get\\Hypotenuse=\sqrt{200}=10\sqrt{2}=10\times 1.414=14.14\ inches$

Therefore the length of the hypotenuse is 14.14 inches.

You want to buy a house in 9 years. The estimated cost is $175,800.00. You want to make a 20% down payment and closing costs are

Vinvika [58]

Given:
estimated cos/purchase pricet: 175,800.00
down payment: 10% of purchase price
closing costs: 7% of purchase price
years to save: 9 years

Down payment:
175,800 * 10% = 17,580

Closing cost:
175,800 * 7% = 12,306

Total cost to save for : 17,580 + 12,306 = 29,886

9 years * 12 months = 108 months

29,886 / 108 months = 276.72 savings per month.
