40 degrees
A ten degree angle is complementary to an eighty degree angle. Complementary angles add up to 90 degrees, so 10 + 80 = 90.
If the triangle has a 30 degree angle and a 60 degree angle then the 3rd angle must be a 90 degree angle because there are 180 degrees in a triangle and so therefore it is a right angle triangle.
100
A triangle with a 90 degree angle and two acute angles is a right angle triangle.
An obtuse triangle is a triangle that has one angle greater than 90 degrees.
The sum of the angles in a triangle equals 180, so the third angle is forty degrees. JTPaulson
A ten degree angle is complementary to an eighty degree angle. Complementary angles add up to 90 degrees, so 10 + 80 = 90.
If the triangle has a 30 degree angle and a 60 degree angle then the 3rd angle must be a 90 degree angle because there are 180 degrees in a triangle and so therefore it is a right angle triangle.
The third angle is 68 degrees which makes it a scalene triangle
Supplement angles add up to one hundred eighty degrees, so the supplement of an eighty five degree angle would be a ninety five degree angle.

In a right triangle the greatest angle is 90 degrees.
a TRIANGLE THAT HAS A 90 DEGREE ANGLE A right triangle is a triangle that has exactly 90 degrees for one angle.
40 degrees
A triangle with a 90 degree angle and two acute angles is a right angle triangle.
What is a 79 degree of a third angle of a triangle
55 degrees because there are 180 degrees in a triangle
