The hypotenuse of a 45-45-90 triangle measures 4 cm. what is the length of one leg of the triangle

2.83 cm.

Step-by-step explanation:

We have been given that the hypotenuse of a 45-45-90 triangle measures 4 cm. We are asked to find the length of one leg of triangle.

We know that hypotenuse of 45-45-90 triangle is and each leg is x units.

We are told that hypotenuse of triangle is 4 cm, so we can set an equation as:

Therefore, the length of each leg of triangle is approximately 2.83 cm.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
