A triangle has two angles that measure 45 degrees and 35 degrees. What is the measurement of the third angle?

Well, we know that a triangle's angles add up to 180°, so 45 + 35 + x = 180, and x = 100.

The third angle is 100.

The measurement of the third angle is 100 degrees.

Step-by-step explanation:

Just add 45 + 35 which equals to 80. Every triangle's angles equal to 180 degrees so subtract 80 from 180. That equals 100 degrees.

Equation: 45+35=80

180-80=100

Hope this helps! :)
