Answer:
D
Step-by-step explanation:
Using the sine ratio in the right triangle
sin B = = = , thus
B = ( ) ≈ 12.84° → D
The total length of the fencing is 248 ft; we call this the "perimeter" of the garden. Since P = 2W + 2L in general, here:
P = 248 ft = 2W + 2(W+6), or 248 ft = 4W + 12.
Subtracting 12 from both sides of this equation: 236 ft = 4W. Then W = 59 ft, which means that L = 65 ft.
Answer:
Step-by-step explanation:
Four consecutive counting numbers would look like this
x
x + 1
x + 2
x + 3
Do you see that these numbers are 1 larger than the one before it. So if x is 20 the numbers would be 20 21 22 23
Now take the 4 general numbers and add them
x + x + 1 + x+2 + x + 3
4x + 6
Two will go into 4x to give 4x/2 = 2x
Two will go into 6 to give 6/2 = 3
Always happens. There are no exceptions. Try x = 20 again
20 + 21 + 22 + 23 = 86
Can this number be divided by 2? Yes it can 86/2 = 43
