Remember that all of the angles on one side of a straight line
add up to 180 degrees.
Here's how to use that factoid to set it up:
The two angles on the same side of the slanted line add up to 180.
(5k + 20) + (3k + 16) = 180 .
Solve that for 'k'. Then ... Both angles on the right side of
the vertical line also add up to 180. So the answer to the
question is
[ 180 - (3k + 16) ].
Just folding my arms and sitting back and looking at all of that,
I got 110 degrees. Do NOT use that for the answer, but I'll be
curious to see if it's anywhere close.
