Answer:
∠N = 31
Step-by-step explanation:
MN = MP
∠N = ∠P = x+3
∠M + ∠N + ∠P = 180
4x+6 + x+3 + x+3 = 6x + 12 = 180
x = 28
∠N = 28 + 3 = 31
Step 
we know that
The density's formula is equal to
The volume of a cone is equal to
where
r is the radius of the base of the cone
h is the height of the cone
in this problem
substitute the values in the formula above
Step 
Find the density
we have
substitute in the formula
therefore
<u>the answer is</u>
the density is 
Answer:
- 83 1/3 ft wide
- 171 2/3 ft long
Step-by-step explanation:
Let w represent the width of the area. Then 2w+5 represents the length. The perimeter is twice the sum of length and width:
P = 2(L+W)
510 = 2(2w+5 +w) . . substitute given values
255 = 3w +5 . . . . . . divide by 2
250 = 3w . . . . . . . . . subtract 5
83 1/3 = w . . . . . . . . .divide by 3; the width of the area
2w+5 = 171 2/3 . . . . the length of the area
The fenced area is 83 1/3 ft wide and 171 2/3 ft long.
Well to start off put 1 and 2 as “given”
