Answer:
127 degrees = x
Step-by-step explanation:
A six sided polygon has interior angles that sum to
(n-2)(180) = (6-2)(180 = 720
so all of the angles in the question add to 720
98 + 133 + x + x + 155 + 80 = 720
solve for x = 127 degrees
I'll do 14 and 18, and you can apply those techniques for the other problems!
For 14, we get 30*(1/10^8). This means that you move the decimal place in 00.0000030.0 seven places to the left, resulting in 0.00000300
For 18, we can use the associative property of multiplication to get
5*3.5*10^3*10^(-1)=17.5*10^2. We get 10^2 by adding 3 and -1 up. Since it's positive 2, we simply move the decimal 2 places to the right to get 1750
<u>Given</u>:
Given that the radius of the circle is 4 units.
The given figure is 
th of the circle.
We need to determine the area of the th of the circle.
<u>Area of the circle:</u>
The area of the circle can be determined using the formula,
Substituting r = 4, we have;
Thus, the area of the circle is 16π units².
<u>Area of the </u><u>th of the circle:</u>
The area of the th of the circle is given by
Therefore, the area of the shape is 12π units².
Answer:
congruent.. because they are opposite another..
Answer:
y = -4x - 7
Step-by-step explanation:
y = mx + b
parallel lines have the same slope m, which in this case is -4
y = -4x + b
now plug in the desired included point to find the y intercept
1 = -4(-2) + b
1 = 8 + b
b = -7
