What is the measure of the third angle of a triangle if one angle measures 25° and the second angle measures 50'?
Lessor

105°

Step-by-step explanation:

total angle of triangle equals 180°

so,

25° + 50° + ? = 180°

? = 180° - (25° + 50°)

? = 180° - 75°

? = 105°

So third angle of a triangle is 105°
