For this case we have that the figure shown consists of 7 sides.
Then a regular heptagono is observed (the sides are equal). By definition, we have that the sum of the internal angles will be given by:
Where:
n: It is the number of sides
Substituting:
Answer:
Option D
Can you rewrite it so that I can understand what you wrote
Answer:
all nonnegative real numbers
Step-by-step explanation:
all nonnegative real numbers give us all nonnegative integers
Answer:
the area of a circle is πr²
the outer circle area = π 4x²
the inside circle area = π.6²=36π
the outer circle area - the inside circle area = he shaded region
π 4x² - 36π =220π cm2 it implies x²-9 =55 and x²=64, and x =sqrt(64)=8
the value of x is 8
Answer:
x = 3
Step-by-step explanation:
Angle S and Angle T are consecutive interior angles. Therefore, we know that T + S = 180°.
First, we need to solve for T, and since angles S and T are consecutive interior angles, we know that T + S = 180°. If we reorganize the equation to include the things we know (S = 105°), then we get 180° - 105° = 75°. So T is 75°.
Now, we use T = 75° and the information given to us in the picture to set up an equation. 75 = 24x + 3. Now, we can find x by isolating it. Do this by:
1) Subtracting 3 from both sides to give you 72 = 24x. We do this to get rid of the 3 from the "x side", but we must also do it to the other to keep the equation true. This moves the 3 from the "x side" to the other since we're trying to isolate x.
2) Divide 24 by both sides to get 3 = x. We use the same logic as we did for 3, except this time we divide since that's the opposite of multiplying.
In conclusion, x = 3.
