Answer:

m∠2 = 40°

Step-by-step explanation:

Because the 2 lines are parallel, that means ∠1 and ∠2 are corresponding angles. Using the Corresponding Angles Theorem, m∠1 = m∠2. Therefore, m∠2 is 40°.

Which choices are real numbers? Check all that apply.

Nonamiya [84]

Answer:

Step-by-step explanation:

Exponents with fractions in them are really just radical notation in a different form. You've probably seen the square root sign.

That can be written as

x^(1/2)

...and when you take an even root of a negative number, there is no real answer. (2 is an even number).

Looking at the answer choices here, we can see that B and D use even roots, so they will give non-real answers.

So, A and C are the answer choices to select.

What is the volume of a cone that has a height of 10 feet and a base with a diameter of 2 and half feet?

lyudmila [28]

Volume of a cone: 1/3 $\pi$ r²h
r is the radius (diameter ÷ 2) and h is the height.

Find the radius first using the diameter: 2 $\frac{1} {2}$ ÷ 2 = 1.25

Now plug in the numbers into the formula.

1/3 $\pi$ 1.25²10 = 16.4

The volume of the cone is 16.4 cubic feet.
