Answer:

60 degrees

Step-by-step explanation:

The angles inside a triangle must add to 180 degrees

60+60+x=180

120+x=180

Subtract 120 from both sides

x=60

So, the third angle is 60 degrees

Hope this helps! :)

Answer: 60 degrees.

Explanation: If two angles measure 60 degrees, that means that the triangle is equilateral and the third angle is also 60 degrees. You can also just add the two given measures and subtract the sum from 180 degrees.
