Answer 1

do you know the Pythagorean theorem

Answer 2

Not really, I don't know anything about it really, it confuses me. I'm home schooled so I've been just skipping it until I HAVE to do it. Which was a REALLY stupid idea.

Answer 3

d

Answer 4

A SQUARED PLUS B SQUARED = C SQUARED

Answer 5

The information given represents lengths of sides of a right triangle with c the hypotenuse. Find the correct missing length to the nearest hundredth. A calculator may be helpful.



a = 16, b = 28, c = ?




A.


31.46


B.


31.94


C.


32.09


D.


32.25

Answer 6

Use the Pythagorean Theorem. Plug in b = 11, c = 17 and solve for 'a' to get


\[\Large a^2 + b^2 = c^2\]


\[\Large a^2 + 11^2 = 17^2\]


\[\Large a^2 + 121 = 289\]


\[\Large a^2 = 289-121\]


\[\Large a^2 = 168\]


\[\Large a = \sqrt{168}\]


\[\Large a \approx 12.96148 \ ... \ \text{ Use a calculator here}\]

\[\Large a \approx 12.96 \ ... \ \text{ Round to 2 decimal places}\]

Answer 7

For the next one, you'll have...

\[\Large a^2 + b^2 = c^2\]


\[\Large 16^2 + 28^2 = c^2\]


and I'll let you finish up
