I assume you mean a TRIANGLE. The angles in a triangle will sum up to 180 degrees. So sum your two angles and subtract that from 180.
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.

The third angle measures 18 degrees.
180- total of the first two angles= 3rd angle
Two of the angles measure 30 and 45. Thus, third angle = 180 - (30+45) = 180 - 75 = 105

Since the sum of all three angles is 180 degrees, the third angle is 180 - 45 - 93 =Since the sum of all three angles is 180 degrees, the third angle is 180 - 45 - 93 =Since the sum of all three angles is 180 degrees, the third angle is 180 - 45 - 93 =Since the sum of all three angles is 180 degrees, the third angle is 180 - 45 - 93 =
Two angles of a triangle add up to 65°. What is the measure of the third angle?
The third angle is (128 degrees) minus (the second angle).
The third angle is [180-(32+70)] = 180-102 = 78
If that's a triangle, the third angle is 90 degrees.
A right angle is one of 90 degrees. An acute angle of 30 degrees would be one third of that.
Assuming the third angle is x... 180 = 15 +85 + x 180 = 100 +x 80 = x The third angle is 80 degrees
The third angle measures 18 degrees.
63 degrees because 180 -39 -78 = 63
