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.
If two angles of a triangle each measure 55 what is the measure of the third angle?
100.
The third angle measures 18 degrees.
The angles are 90 degrees, 57 degrees and the third angle is 33 degrees

If two angles of a triangle each measure 55 what is the measure of the third angle?
55°
100.
Two angles of a triangle add up to 65°. What is the measure of the third angle?
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 =
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.
