Question

A right triangle has one side of length 8 and a hypotenuse of length 10. How long is the third side of the triangle?

Answer 1

Pythagorean Theorem

a^2 + b^2 = c^2

Do you know which one has to be c?

Answer 2

No I do not

Answer 3

the hypotneuse --------> 10

so

c=10 and a = 8

substitute

8^2 + b^2 = 10^2

or

64 + b^2 = 100

do you know the next step?

Answer 4

nope

Answer 5

subtract 64 from both sides

b^2 = 36

Next step?

Answer 6

Do I simplify after this?

Answer 7

Yes we have been simplifying ...

Answer 8

So would you get b^2=36?

Answer 9

and simplify this ...

Answer 10

Would it be the square root of 36?

Answer 11

yes. Nice job!
