The sum of the three interior angles in a triangle is always 180 degrees. If two angles in a triangle add up to 125 degrees, subtracting this sum from 180 gives you the measure of the third angle. Therefore, the third angle would be 180 - 125 = 55 degrees.

The idea here is to use the fact that the sum of all three angles is 180 degrees.

The sum of the measure of two angles of a triangle is 95 degrees What is the measure of the third angle?

The third angle is 85 degrees. The sum of all internal angles in a triangle is always 180 degrees


What is a triangle with angles of 60 degrees and 30 degrees?

The third angle has to be 90 degrees so it would be a right angle triangle.


What is the third angle of a triangle if the sum of the other two angles is 148 degrees?

The sum of the angles of a triangle is 180 degrees. If the sum of two of a triangle's angles is 148, then the third angle must be 180 - 148 = 32 degrees.


How do you determine the third angle of a triangle if 2 angles are known?

There are 180 degrees in a triangle. So, if you subtract two angles (angles A and B) from 180 degrees, you get the third angle (angle C). So: 180 - A - B = C


A triangle has one angle of 80 degrees an another of 60 degrees how many degrees must there be in the third angle?

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.


What if two angles of a triangle are complemenatr what is the measure of the third angle?

The sum of two complementary angles is 90 degrees. The three angles of a triangle add up to 180 degrees. Hence, if you subtract the complementary angles from 180, you have the measure of the third angle: 180 - 90 = 90 (this is the third angle) As a rule, if two angles of a triangle are complementary, the third angle is a right angle (90 deg). The three angles together form a right triangle.


If two angles in a triangle are 120 degrees what would the third angle be?

The premise is impossible. The sum of the angles of a triangle is 180 degrees.

What is the measure of the third angle of the triangle?

The third angle of a triangle is equal to 180 degrees minus (the sum of the first two angles).

The third angle is 93 degrees


What is the measure of the third angle of a triangle if one angle measures 15 degrees and the other measures 85 degrees?

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.


Find the third angle of a right triangle if the measure of on of the angles is 68?

The sum of interior angles of any triangle is 180 degrees. A right triangle is defined as a triangle having one angle that measures 90 degrees. Therefore, it follows that the sum of the remaining two angles will be 90 degrees 90-68=22 The third angle is 22 degrees
