PLEASE HELP ASAP

The leg of a right triangle is 3 units and the hypotenuse is 4 units. What is the length, in units, of the other leg of the triangle?

Square root of 5
Square root of 7
5
7

Answer 1

a leg of a right triangle can never be greater then the hypotenuse

this formula will tell you if it's a valid right triangle

`{?}^(2) + {?}^(2) = {?}^(2)`
the first two question marks are the legs of the triangle while the one after the = is the hypotenuse.

THE STEPS:

`{3}^(2) + { √(7)^(2) } = {4}^(2)`

`9 + {2.65}^(2) = 16`

`{2.65}^(2) = 7`

`9 + 7 = 16`
ANSWER:
`√(7)`
