Question

Use the Pythagorean Theorem to find the missing length and then round the result to the nearest tenth a=? b = 5, c = 12 what is A​

Answer 1

Approximately 10.9

Explanation:

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

Plug in b (5) and c (12)

`a^2+5^2=12^2\\a^2+25=144`

Subtract 25 from both sides

`a^2+25-25=144-25\\a^2=119`

Take the square root of both sides

`√(a^2) =√(119)`

a = approximately 10.9
