Question

Find the missing length using the Pythagorean theorem. Show your steps.

Answer 1

4cm

Step-by-step explanation: Remember that the Pythagorean theorem is
`c^2 = a^2 +b^2`

c will be the hypotenuse which is 5cm

a will be the horizontal side which is 3cm

Time to set it up:
`5^2=3^2+b^2`

`25=9+b^2`

From here we'll just solve for b and then square root for the answer.

`25-9=b^2\\`

`16=b^2\\ 4=b\\`

Answer 2

34 cm

Explanation:

Because 5^2+3^2=x^2 5^2 is = to 5*5 so 25 then 3^2 =3*3 is 9 last but not less 25+9=34
