Answer: The two angles add up to 180 so they are supplementary angles.
The sum of their measures is 180 degrees.
Step-by-step explanation:
Plug in given value for x.
x=20
(3x+50)=
(60+50)=110
110
(4x-10)=
80-10=70
70
There are several true things about these angles you can find from this information but I think you are looking for the answer at top.
You have to move the decimal 2 places over so like if it’s 2.00 the percent would be 200%, and if it was .20 it would be 20%
Answer:
x = 45
x = 19
Step-by-step explanation:
A straight line = 180°
So,
12.
3x + x = 180
4x = 180
---- -----
4 4
x = 45
13.
(5x + 4) + (x - 2) + (3x + 7) = 180
Combine like terms:
(5x + 4) + (x - 2) + (3x + 7) = 180
9x + 4 - 2 + 7 = 180
9x + 9 = 180
-9 -9
------------------
9x = 171
----- -----
9 9
x = 19
Hope this helped.
Answer:
x = y − 6 Is your answer
Step-by-step explanation:
y = x + 6
x = y -6
Answer:
Step-by-step explanation:
are equal in measure. If two parallel lines are cut by a transversal, the alternate exterior angles are congruent. If two lines are cut by a transversal and the alternate exterior angles are congruent, the lines are parallel.
