Two angles of a triangle are 40 degrees and 62 degrees ; what is the third angle’s measure ?

The measure of the third angle = 78°

Step-by-step explanation:

∵ The sum of angles in any triangle = 180°

∵ The measures of two angles are 40° and 62°

∴ The measure of the third angle = 180 - (40 + 62) = 78°

78 degrees.

Step-by-step explanation:

By definition, the sum of the interior angles of a triangle is 180 degrees.

Then, keeping on mind that two angles of a triangle are 40 degrees and 62 degrees, you can calculate the third angle as following, where x is the missing angle:

Therefore, the third angle measures 78°.
