Answer:
Explanation:
We can find the angle directly above the
.
We know that because they both lie on a straight line, the other angle is
.
Aha! We have a path to the solution!
because of the parallel line angle theorem(I forget what it's called).
We then add
and
to both sides to get
.
Lastly, we divide by
to get
.
So,
and we're done!
