Question

Help me please help me

Answer 1

82 cm

Explanation:

The equation they are giving you is the pythagorean theorem, which is used to calculate the diagonal or hypotenuse of a triangle:

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

We are given dimensions of 42 and 71, so we can plug in those values:

`41^2+71^2=c^2\\1681+5041=c^2\\6772=c^2\\√(6772)=c\\ 82.292=c\\`

So, the correct answer will be 82 cm, as we are giving the closest answer.

Hope this helps! :)

Answer 2

82cm

Explanation:

a2 + b2 = c2

c2 is the hypotenuse always

`71^(2) +42^(2)` =
`c^(2)`

6805 =
`c^(2)`

then square root the c and 6805 to isolate c

c = 82.49
