Lines AB and CD are parallel. If 6 measures (3x - 33)°, and 5 measures 123°, what is the value of x?
1 answer:
The value of x from the figure is 30 degrees
<h3>Parallel lines</h3>Parallel lines are lines that have the same slope and have 0 degrees as the angle between them.
The sum of angle 5 and angle 6 are supplementary. Hence;
m<5 + m<6 = 180
3x - 33 + 123 = 180
3x + 90 = 180
3x = 180 - 90
3x = 90
Divide both sides by 3
3x/3 = 90/3
x = 30
Hence the value of x from the figure is 30 degrees

Step-by-step explanation:
for question a)
It would be easier if you converted these to improper fractions (currently it is in the form of a proper fraction)
to convert to improper fraction, you would multiply the denominator (bottom no. of fraction) by the whole number , then add that with the numerator (top no. of fraction) and put the whole thing over the denominator.
E.g.
7 = 7x4 + 1 = 29
Thus, improper fraction would be
do same thing for other one
thus ,
now,
-
however, you can't do this as the denominators are not the same, so multiply them by a number which would give the a common denominator (20 would be the best option for common denominator)
