Question

Can someone help me with these 3 questions? I need them asap (Test) Screenshots are below! I will give 15 pts!

Answer 1

Pythagorean Theorom:
`a^2+b^2=c^2`

Triangle #1

`21^2+x^2=29^2`

`x^2=29^2-21^2`

`x=√(841-441) =√(400)=20`

Triangle #2

`1.6^2+3.0^2=x^2`

`x=√(1.6^2+3.0^2)=√(11.56) =3.4`

Triangle #3

`x^2+40^2=41^2`

`x=√(41^2-40^2)=√(81) =9`

I hope this helps!
