I honestly believe that the scientific method will not be useful for me in the future
Answer:
144°
Step-by-step explanation:
step 1
Find the measure of the central angle of the regular pentagon
Divide 360 degrees by 5 (the number of sides)
Let
c----> the center of the pentagon
we know that
m∠ECA=72°
m∠ACB=72°
therefore
m∠ECB=m∠ECA+m∠ACB
substitute the values
m∠ECB=72°+72°=144°
The measure of angle ECB is equal to the degrees that the pentagon rotate
Answer:
It is 1,965.74 square feet
Step-by-step explanation:
the area of the circle is πr^2 so if you substitute the variables with the numbers you get, π29^2=841π=841*3.14=2640.74
the area of the triangular flowerbed is 1/2bh=1/2*27*50=675
if you want to find the grass area you would need to subtract the triangular area from the circle, which is 2640.74-675=1965.74 square feet
Answer:
The graph has a closed circle.
–7 is part of the solution.
Step-by-step explanation:
Given
Required
Select 3 options from the given list of options
Subtract 22 from both sides
Swap positions of the expression; Note that the inequality sign will change
This means <em>x less-than-or-equal-to negative 7</em>
<em></em>
There are two options left to select;
The inequality sign in implies that the graph has a close circle.
Inequality signs such as and signifies a close circle
There is only one option left to select;
Lastly;
Split the expression into two
We have:
or
Because ,
Then, -7 is also a part of the solution
Answer:
A = 7
Step by step:
11 - 4 = 7
So,
7 + 4 = 11
