Answer:
The radius is half of the diameter of the circle and it is measured from the center of the circle to the circumference of the circle.
Step-by-step explanation:
Answer:
2x+50 and 5x-55 both are congruent or have same measure.
Step-by-step explanation:
Since we want to prove that both lines are parallel, this means no theorems that involve with parallel lines apply here.
First of, we know that AC is a straight line and has a measure as 180° via straight angle.
x+25 and 2x+50 are supplementary which means they both add up to 180°.
Sum of two measures form a straight line which has 180°.
Therefore:-
x+25+2x+50=180
Combine like terms:-
3x+75=180
Subtract 75 both sides:-
3x+75-75=180-75
3x=105
Divide both sides by 3.
x=35°
Thus, x = 35°
Then we substitute x = 35 in every angles/measures.
x+25 = 35°+25° = 60°
2x+50 = 2(35°)+50° = 70°+50° = 120°
5x-55 = 5(35°)-55 = 175°-55° = 120°
Since 2x+50 and 5x-55 have same measure or are congruent, this proves that both lines are parallel.
Solve the equation
So first we subtract 8 from both sides because we apply the inverse operation.
-2x+8=-16
-8 -8
Now we apply it and re write the equation
-2x=-24
Now the inverse operation for multiplication is division, so we apply it.
-2x=-24
------------
-2 -2
We are left with x=8
So our final answer is x=8
Check our work
-2(8)+8=-16
CORRECT ANSWER. :)
