Answer:
10.44
Step-by-step explanation:
First plot each of the points on to a graph at their respective positions.
Following that create a 90° triangle out of the points. This will create a 3 by 10 triangle. (3 to 0 is 3) (-8 to 2 is a difference of 10)
You can then use the pythagorean theorem 
.
Insert the lengths of each of the sides that we got earlier which would be 3 and 10 into the equation. 
Since we want to find the hypotenuse which is equal to c we work the equation to 9+100 = 
which in turn is 109 =
Then take the square root of 109 to remove the square from the c to get c = 10.44
Answer:
55°
Step-by-step explanation:
Since a||b
Then corresponding angles are equal
So 55 is correspondent to X
Therefore X=55°
I don't knowhhhhh hhhhhhhhh hhhhhhhh
Answer:
C. 70°
Step-by-step explanation:
The inscribed angle marked 15° intercepts an arc that is double that measure, so the intercepted arc on the right is 2×15° = 30°.
The external angle marked 20° is half the difference of the intercepted arcs, so is ...
20° = (1/2)(x - 30°)
40° = x - 30° . . . . . . multiply by 2
70° = x . . . . . . . . . . . add 30°
The value of x is 70°.
Answer:
y = x +3
Step-by-step explanation:
When you examine the table, you see that each y-value is 3 more than the corresponding x-value. This is represented in the equation ...
y = x +3
