Answer:

perimeter = 126

Step-by-step explanation:

A regular nonagon with sides measuring of 14 has 9 equal sides that are 14 units long each.

To find the perimeter, you multiply the number of sides by the side length.

9 × 14 = 126

15 points please help!! :)<br> Find the value of x.
andriy [413]

Answer:

Question 4: -11

Question 5: -7

Step-by-step explanation:

Four

Every triangle has 180 degrees.

So all three angles add to 180

<em><u>Equation</u></em>

60 + 80 + x + 51 = 180

<em><u>Solution</u></em>

Combine the like terms on the left. This is the first time I've seen x be a negative value. Almost all of the time it isn't, which should make you wonder.

191 + x = 180    

Subtract 191 from both sides.

191 - 191 + x = 180 - 191

x = - 11

Five

If a triangle is a right triangle and one of the angles is 45, then so is the other one.

<em><u>Proof</u></em>

a + 45 + 90 = 180         Combine like terms on the left

a + 135 = 180                Subtract 135 on both sides.

a + 135-135=180-135    Combine the like terms

a = 45

<em><u>Statement</u></em>

That means 52 + x = 45 and here is another negative answer. Subtract 52 from both sides

52 - 52 + x = 45 - 52    Combine like terms.

x  = - 7

That's a rectangular prism.

And the formula to find the volume of a rectangular prism is:

\sf~A=lwh

Plug in what we know:

\sf~A=(9)(2)(6)

Multiply the three numbers together:

\sf~A=\boxed{\sf108}
