Answer:
Equation to solve is x+x+120=180
Solution to equation: x=30
Step-by-step explanation:
The angles in a triangle have a sum 180 degrees.
You know one angle is 120 degrees.
If you assume another angle has a measurement of x degrees, then the remaining angle has a measurement of x degrees. We know this because congruent means they will have the same measurement.
So we have this equation to solve:
x+x+120=180
Combine like terms:
2x+120=180
Subtract 120 on both sides:
2x=180-120
Simplify:
2x=60
Divide both sides by 2:
x=60/2
Simplify:
x=30
Answer:
x = 6
Step-by-step explanation:
5x - 11 = 19
+11 = +11
5x = 30
5x/5 = 30/5
x = 6
Answer: multiply the radius times 2 and then multiply the result by 3.14.

Answer:
Step-by-step explanation:
So, we know the slope is -5/6. From here we can write this equation:
In the question they give us both the x and y in this equation (-6,4)
Plug them in to the equation and solve for b:
Now, we can write the equation as follows:

The given equation is in the point-slope form. The slope can be obtained by simple identification of the parts of the equation. This is shown below:
Given equation:
(y - 3) = -2 (x - 4)
y - y1 = m(x - x1)
Where slope, m = -2
The slope of a line perpendicular to the line CD is the negative reciprocal of the slope of the line CD. Therefore:
Slope = 1/2
