Question

How do I answer this Question? It’s phythagoras theorem!

Answer 1

C = 11.18 D= 20

Explanation:

Let's start with C

Square root both areas of the squares

`√(25) =5`

`√(100)=10`

Then use the Pythagoras Theorem:
`a^(2) +b^(2) =c^(2)`

`10^(2) +5^(2) =125`

`√(125) =11.18033989` = C

Moving on to D

Square root both areas of the squares

`√(841) =29`

`√(441) =21`

29 is the hypotenuse, we are trying to find the other leg, so:

`29^(2) -21^(2) =400`

`√(400) =20` = D
