Question

In a right-angled triangle, the hypotenuse is 113 and a leg is 112.

Determine the length of the other leg.

Answer 1

Answer: 15

Step-by-step explanation: Use the formula:
`a^(2)+b^(2)=c^(2)`

Remember
`c^(2)` should always be the hypotenuse or the longest side.

`112^(2)+b^(2)=113^(2)` ---> evaluate the exponents

`12544+b^(2)=12769` ----> subtract 12544 to the other side

`b^(2)=225` ---> take the square root of both sides

`b=15`
