Respuesta :
The value of a = 63º.
Two parallel lines are crossed by a transversal.
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, 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
Therefore, the value of a is:
a = 63º.
