The angles below are supplementary. What is the value of x?
2 answers:
A line is 180 degrees Subtract that 80 degrees to only single out the other half (100) Subtract 40 so that you can single it out to just 3x (60) Then divide your answer from the previous by three to cancel you coefficient and get your final x (60/3) X will be equal to 20 Hope this helps! :)
Answer:
x= 20
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
The first angle is 3x+40 and the second angle is 80. The add together to form a straight line. The straight line is 180 degrees.
3x+40 + 80 = 180
Combine like terms
3x+120 = 180
Subtract 120 from each side
3x+120-120=180-120
3x = 60
Divide each side by 3
3x/3 = 60/3
x = 20
