Answer:
<h2><u><em>
144°</em></u></h2>
Step-by-step explanation:
regular decagon = all side equal and all angles congruent, so your answer is 144°
Answer:
B.
Step-by-step explanation:
The ratio of the lengths of the sides of a 30-60-90 triangle is
1 : sqrt(3) : 2
From the 1 and 2, we see that the hypotenuse must be twice the length of the short leg.
From the 1 and sqrt(3) we see that the long leg is sqrt(3) times the length of the short leg.
Now we check for these two ratios in each choice.
A.
1 is twice 1/2. Check
sqrt(3)/2 is sqrt(3) times 2. Check
B.
10 is twice 5, not twice 5/2. This does not check.
C.
2sqrt(2) is twice sqrt(2). Check
sqrt(6) is 2sqrt(2) time sqrt(3). Check
D.
6 is twice 3. Check
3sqrt(3) is sqrt(3) times 3. Check
Answer: B.
To solve divide both sides by 4 to cancel out the 4 on the x side to get x alone. Then just do -10/4. That gives you 2.5 so (X=2.5). Hope I helped and have a great day and night
F(x) = 25 - 2x
f(5) is pretty much the value of f(x) when x = 5
Plug x=5 into f(x)
f(5) = 25 - 2(5)
= 15
That's your answer.
Have an awesome day! :)
Answer: a) 92 yards, b) 29.29 yards and 672.99 sq. yd.
Step-by-step explanation:
Since we have given that
Area of square pen = 529 sq. yd
Let the length of each side be 'a'.
As we know the formula for "Area":

So, the perimeter of the square pen is given by

So, perimeter of square pen = Perimeter of round pen

So, the diameter of round pen is 
And the area of round pen is

Hence, a) 92 yards, b) 29.29 yards and 672.99 sq. yd.
