The sum of the three angles in a triangle is 180 degrees. one of the angle measures 30 degrees, and the second angle measures 75 degrees. what is the measure of the third triangle?

the measure of the third triangle is 75 degrees.

Step-by-step explanation:

Let the measure of the third angle be x degrees.

The sum of the three angles in a triangle is 180 degrees.

One of the angle measures 30 degrees, and the second angle measures 75 degrees. Therefore,

30 + 75 + x = 180

105 + x = 180

Subtracting 105 from the left hand side and the right hand side of the equation, it becomes

x = 180 - 105 = 75 degrees
