The hypotenuse of a right triangle measures 13 cm and one of its legs measures 1 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.

Answer 1

13*

Explanation:

Use the Pythagorean theorem.

a=1

b=x

c=13

so,
`1^2 + x^2 = 13^2`

`x^2 = 169 - 1 = 168`

`x = √(168)`

`√(168) = 12.961481396815720461931934872176` = 13

*If we round to the nearest tenth, we get 13. Because of this rounding, the other leg is the hypotenuse, but it is actually different.
