Answer:

4th choice, 20, 21, 29 would be the answer.

Step-by-step explanation:

Pythagorean Theorem: a^2 + b^2 = c^2

a= 20, b= 21, c= 29 ( c has to be the C, hypotenuse, because it is the longest)

therefore,

20^2 + 21^2 = 29^2

into

400 + 441 = 841,

which is true, makes the Pythagorean Theorem work.

ra1l [238]

Answer:

$104,167 approx.

Step-by-step explanation:

Step one:

Given data

Morgan made $12,500 on the sale of a home.

Her commission she earns in selling homes is 12%

Step two:

let the cost of the home be x

So 12% of x= 12,500

12/100*x= 12,500

0.12*x=12,500

0.12x=12,500

divide both sides by 0.12

x= 12,500/0.12

x=$104,166.66

x=$104,167
