Question

PLEASE HELP ASAP
Numbers are 17 cm 23 cm if you can’t see

Answer 1

Answer: 15.5

Step-by-step explanation:c squared - b squared = a squared

Answer 2

15.5 cm

Explanation:

Since this is a right triangle and we have to solve for an unknown side, we can use the Pythagorean Theorem, which is:

`a^2+b^2=c^2`.

Note that a and b is one of the legs, but c is always and must be the hypotenuse.

We know one of the legs is 17 and the hypotenuse is 23. Let's put these numbers in (you can put 17 in for either a or b, it doesn't matter, but the 23 must replace c).

`17^2+b^2=23^2`

`289+b^2=529`

`b^2=240`

`b=√(240)=4√(15) \approx 15.5`
