Answer: 19
Step-by-step explanation: when two negative signs are next to eachother, you need to add the two numbers.
Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
For lines to be parallel, they have to have the same slope.
y = 6x + 6 The slope of this line is 6, so the parallel line's slope is also 6.
Now that you know m = 6, substitute/plug it into the equation:
y = mx + b Plug in 6 for "m" in the equation
y = 6x + b To find "b", plug in the point (20, 1) into the equation
1 = 6(20) + b
1 = 120 + b Subtract 120 on both sides to get "b" by itself
1 - 120 = 120 - 120 + b
-119 = b Now that you know b = -119, plug it into the equation
y = 6x - 119

![\large\boxed{C=87.92\ in}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7BC%3D87.92%5C%20in%7D)
Step-by-step explanation:
The formula of an area of a circle:
![A=\pi r^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2)
r - radius
We have A = 615.44 in². Substitute:
![615.44=\pi r^2](https://tex.z-dn.net/?f=615.44%3D%5Cpi%20r%5E2)
![\pi\approx3.14](https://tex.z-dn.net/?f=%5Cpi%5Capprox3.14)
<em>divide both sides by 3.14</em>
![r^2=196\to r=\sqrt{196}\\\\r=14\ in](https://tex.z-dn.net/?f=r%5E2%3D196%5Cto%20r%3D%5Csqrt%7B196%7D%5C%5C%5C%5Cr%3D14%5C%20in)
The formula of a circumference of the circle:
![C=2\pi r](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r)
Substitute:
![C=2\pi\cdot14=28\pi\approx28\cdot3.14=87.92\ in](https://tex.z-dn.net/?f=C%3D2%5Cpi%5Ccdot14%3D28%5Cpi%5Capprox28%5Ccdot3.14%3D87.92%5C%20in)
Answer:
B) No, supplementary angles are either of two angles whose sum is 180 degrees.
C) Yes, the triangles are congruent because the triangles have exactly the same size and shape
Step-by-step explanation:
B) From the image below an 180 degree angle would be obtuse in which neither angle appears to be so they are not supplementary.
C) They are congruent because they are taking angles of the same angles as one another just on different sides of the shape.
