Question

Find the unknow side of the right triangle 2. b=73.6 cm b= 19.0

Answer 1

Assumed 73.6cm is the hypotenuse.


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

`19^(2) + b^(2) = 73.6^(2)`

`b^(2)` =
`73.6^(2) -19^(2)`

`b^(2)` =
`5055.96`

`b` =
`71.1`

Assumed 73.6cm is not the hypotenuse.

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

`19^(2) + 73.6^(2) = c^(2)`

`c^(2)` =
`73.6^(2) +19^(2)`

`c^(2)` =
`5777.96`

`c` =
`76.0`
