On a piece of paper, use a protractor to construct a triangle with angle measures of 40 degrees and 60 degrees. what is the measure of the third angle? a.) 60 degrees b.) 80 degrees c.) 100 degrees d.) 180 degrees

80

Step-by-step explanation

Well every triangle has to equal 180 degrees.

So you would add the two degrees you already have, which on this one you would get 100.

Then, you would subtract that number from 180 to get 80.

Hope this helps you!!
