The third angle measures 100°.

Step-by-step explanation:

The sum of the measures of the angles of a triangle is 180 degrees.

Let the unknown angle be x.

x + 50 + 30 = 180

x + 80 = 180

x = 100

Answer:

100 degrees

Step-by-step explanation:

All triangles equal up to 180 degrees, so to find the missing angle, you would subtract 180 by the two angles you are given.

So 180 - 50 - 30 = 100

So the third angle of the triangle is 100 degrees.
