40 degrees
Mathematically there are 180 degrees in a triangle. So 180 -60 -80 = 40 degrees which is your answer
77 degrees
If that's a triangle, the third angle is 90 degrees.
30 degrees
If two angles of a triangle are complementary, it means they add up to 90 degrees. Since the sum of the angles in a triangle is always 180 degrees, the third angle would be 180 degrees minus 90 degrees, which equals 90 degrees. Therefore, the measure of the third angle in this triangle would be 90 degrees.
The other acute angle in that triangle is 40 degrees.

The sum of the angles in a triangle equals 180, so the third angle is forty degrees. JTPaulson
The sum of the angles of a triangle is 180 degrees. So we have: 80 + 60 = 140 degrees, the sum of the two angles of the triangle 180 - 140 = 40 degrees, the measure of the third angle. Thus the measure of the third angle is 40 degrees.

There are 180 degrees in a triangle 180 -80 -60 = 40 degrees Answer: 40 degrees
Because the sum of the interior angles of a triangle must equal 180 degrees, the third angle must equal 180-80-60 = 40 degrees.
If that's a triangle, the third angle is 90 degrees.
30 degrees
The third angle is 90 degrees so it is right angle triangle.
The sum of the measures of the angles of a triangle is 180 degrees. First, calculate the sum of the two known angles. Then subtract that result from 180. That difference is the measure of the third unknown angle. Given: One angle of a triangle is 15 degrees and the second angle of the triangle is 85 degrees. To find: We need to find the third angle of the triangle. Let the third angle of the triangle be x. We know that the sum of the angles in a triangle is 180 degrees. ==> 15 degrees + 85 degrees + x degrees = 180 degrees. ==> 100 degrees + x degrees = 180 degress. ==> x = 180 degrees - 100 degrees. ==> x = 80 degress. Therefore the third angle of the triangle is 80 degrees.
