Question

the sum of two angles in a triangle is 100degrees what is the measure of third angle​

Answer 1

Answer:

Since the interior angles of any triangle must always add up to 180 degrees, the third angle must be 100 degrees. All triangles have 180 degrees total in the interior. If we add 35 and 45 we get 80. If we subtract 80 from 180 we get 100 degrees.

Answer 2

Answer:

Since the interior angle of any triangle must always add up to 180° . The third angle must be 100° . All triangle have 180° in the interior
