The lengths of two sides of a right triangle are 12 inches and 15 inches. What is the difference between the two possible length
andrew11 [14]

we know that

In a right triangle

Applying the Pythagorean Theorem

c^{2} =a^{2} +b^{2}

where

a and b are the legs of the triangle

c is the hypotenuse of the triangle

Step N 1

<u>Assume that the third side is a leg</u>

In this case we have

a=12\ in\\c=15\ in\\ b=?

c^{2} =a^{2} +b^{2}

Solve for b

b^{2}=c^{2} -a^{2}

substitute the values

b^{2}=15^{2}-12^{2}

b^{2}=81

b=9\ in

Step N 2

<u>Assume that the third side is the hypotenuse</u>

In this case we have

a=12\ in\\b=15\ in\\ c=?

c^{2} =a^{2} +b^{2}

substitute the values

c^{2}=12^{2}+15^{2}

c^{2}=369

c=19.2\ in

Step N 3

<u>Find the difference of the third sides</u>

19.2\ in-9\ in=10.2\ in

therefore

<u>the answer is</u>

10.2\ in

You just bought a cell phone for $14.99. 100 minutes for your phone, including tax, cost $21.99 per month.
agasfer [191]
Y = m x + b
A linear equation is:
y = 21.99 x + 14.99 ,
where x is the number of months of service.
y = 21.99 * 12 + 14.99 = 263.88 + 14.99 = $278.87
