Answer:

It is B.   (36√5 + 36) ft^2.

Step-by-step explanation:

Total area = area of the base +  4 * area of the triangular side.

The slant height of a triangular side =  √(6^2 + 3^2)

= √45

= 3√5

The area of this side = 3 * 3 √5

= 9√5.

Therefore the total area of the pyramid

=  6^2 + 4*9√5

= (36 + 36√5) ft^2.

Answer:

see below

Step-by-step explanation:

6 1/2 = 6  + 1/2 *3/3 = 6 + 3/6

4 5/6

 6 3/6

-4  5/6

-----------------

We need to borrow from the 6

6 3/6 = 5 + 6/6 + 3/6 = 5 9/6

5 9/6

-4 5/6

--------------------

1  4/6

We can simplify 4/6 to 2/3

Solution: 1 2/3

\frac{1}{3} (n + 15) = -2

First, replace the numerator with the parentheses.
\frac{n+15}{3} =-2
Second, multiply both sides by 3.
n + 15 = -2 * 3
Third, multiply 2 × 3 to get 6.
n + 15 = -6
Fourth, take away 15 from each side.
n = -6 - 15
Fifth, simplify -6 - 15 to get -21.
n = -21

Answer: n = -21

What is the value of E?
kozerog [31]
Hello!

∠E and the angle measuring 119 degrees (we'll refer to this as ∠A) can be classified as supplementary angles. Supplementary angles are two angles whose measures add to a sum of 180 degrees (a straight line). Therefore, we can conclude that sum of ∠E and ∠A is 180 degrees. We can use this information to create the following equation:

∠E + 119 = 180

Now subtract 119 from both sides of the equation:

∠E = 61

We have now proven that ∠E is equal to 61 degrees.

I hope this helps!
