Question

Use the Pythagorean Theorem to find the missing length and then round the

result to the nearest tenth.
a = 8, b = 3, c =

Answer 1

c = 8.5

Explanation:

The Pythagorean theorem is

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

Since we know a and be, we simply square them, then add those values together, and take the square root of the final value

`8^(2) = 64`

`3^(2) = 9`

`64 + 9 = 73`

`√(73) = 8.5`

c = 8.5

Answer 2

~8.5

Explanation:

Knowledge Needed

Pythagorean Theorem:

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

Plug in 2 known values to solve.

Question

`a^2+b^2 = c^2\\(8)^2 + (3)^2 = c^2`

64 + 9 = c^2

c^2 = 73

Find the square root of both sides.

`√(c^2) = √(73)`

c =
`√(73)`

~8.5
