Answer:

<h2><u>x = 15 ft.</u></h2>

Step-by-step explanation:

Using Pythagoras Theorem:

x^{2} + 8^{2} = 17^{2}

⇒ x^{2} = 17^{2} - 8^{2}

⇒ x = \sqrt{(17^{2} - 8^{2})}

⇒ x = \sqrt{(289 - 64)}

⇒ x = \sqrt{(225)}

⇒ x = 15 ft.

Amanda increased the amount of protein she eats everyday from 48g to 54 g By what percentage did Amanda increase the amount of p
xeze [42]

Step-by-step explanation:

she increased the amount from 48g to 54g. that is 54-48 = 6g.

so, the question really is, how many % of 48 is 6 ?

100% = 48g

1% = 100%/100 = 48/100 = 0.48g

how many % are 6g ?

as many as how often 1% (0.48g) fits into 6g :

6 / 0.48 = 12.5%
