What is m∠PLM? m∠PLM = __ °
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.
