Answer:
x = 8
Step-by-step explanation:
The angle above the 6x-8 = 180 -140 = 40
The angle on the opposite side is 40 degrees as well because they are vertical angles
6x-8 = 40 degrees
Add 8 to each side
6x= 48
Divide by 6
6x/6 = 48/6
x = 8
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!
I think it's cost price
I heard it before somewhere
Hope I've been any help to you
Angle 2 and 8 are alternate interior angles. Alternate interior angles are the angles<span> that are formed on opposite sides of the transversal to the two lines and inside the two lines. In this case, t is the transversal to lines m and n. </span>
