A. 12.21

Step-by-step explanation:

Define and explain:

This a right triangle, so the Pythagorean Theorem applies. The Pythagorean Theorem states that the sum of the squared legs is equal to the squared hypotenuse.

The legs of a triangle are the sides that form the right angle.

The hypotenuse is the longest side.

Formula:

Here, I am solving for the hypotenuse.

The last step is to find the square root of 149.

The square root of 149 is irrational, of course, so I must round the square root to the nearest hundredth.

≈

Conclude:

I, therefore, believe the length of the hypotenuse is 12.21.

there are no answer choices

step-by-step explanation:

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.
