Answer 1

The third angle of the triangle measures 65°.

Step-by-step explanation:

A triangle always has a sum of angles equal to 180°. To find the third angle, we can subtract the sum of the given angles from 180°. So, 180° - (42° + 73°) = 65°. Therefore, the third angle of the triangle measures 65°.
