Answer :
Answer: 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:
[tex]x+62+40=180\\x=180-62-40\\x=78[/tex]
Therefore, the third angle measures 78°.

Answer:
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°
