Question

PLEASE HELP QUICKLY

Answer 1

Answer: 10.7 or 10.8

Explanation:

so, first
`a^(2) +b^(2) =c^(2)`

while
`a = 3.75` and
`b=10` and
`c=?`

so, it will be written as,

`3.75^(2) +10^(2) =c^(2) \\`

`14.0625+100=c^2`

`114.0625=c^2` then square root both sides to have an answer of:

`10.7=c`

That's if you are going to use the
`a=3.75`. as written in the question...

while if you're going to use
`a=4` (as shown in the figure) then only change the 3.75 with 4.

which will equal to...

`4^2+10^2=c^2`

`16+100=c^2`

`116=c^2` then square root both sides to have an answer of:

`10.77=c`

`10.8` ≈
`c`

hope you've understanded.!

Answer 2

Ok I don’t understand why it’s 4 ft that’s labeled instead of 3.75 ft but I’m going to assume it’s 4 you’re using.

The pythagorean theorem is basically the 1 leg squared + 2nd leg squared = slanted side (hypotenuse) squared. Or a squared + b squared = c squared

Plug in.

4^2 + 10^2 = c^2
16 + 100 = 116
Square root of 116 (rounded): 10.77 or 10.8
