Question

A right triangle has legs measuring 18 in. and 26 in.

What is the length of the hypotenuse?

Round to the nearest tenth.


18.8 in.

31.6 in.

44.0 in.

100.0 in.
i know the answer but I need someone to explain to me how to do this, I do a^2+b^2 +c^ and i keep getting 26

Answer 1

The answer is 100 in

Explanation:

The pythagorean theorm states that, for any right triangle where a and b are the legs and c is the hypotenuse, a^2 + b^2 = c^2. So, we can substitute and solve.

18^2 + 26^ 2 = c^2

324 + 676 = c^2

1000=c^2

Square root of 1000 = c

100.0=c

Hope this helps!
