Two parallel lines are crossed by a transversal what is the value of a?

For this case, the first thing to do is to observe that the angle between line f and line h equals 63 degrees.
Then, since line f is parallel to line g, then the angle between line h and line g is equal to the angle between line h and line f.
Therefore, we have to:
a = 63º

the value of a is:

a = 63º

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
