The measure of the first angle in a triangle is 60 degrees, the second angle is 90 degrees. How many degrees is the measure of the third angle? Degrees.

If it’s out of 180 degrees it’s 30 degrees

The answer is 30 degrees. The angles in a triangle have to add up to 180 degrees, so add the ones that are given (90°+60°) which equals 150°, and subtract 180°-150°, and you get the measurement of the missing angle, which is 30°
