What is the value of the missing angle 720, 120, 128, or 138?
The sum of the angles in any triangle is always 180 degrees. Therefore, if we add up the given angles of 720, 120, and 128, we get:
720 + 120 + 128 = 968
To find the missing angle, we need to subtract this sum from 180:
180 - 968 = -788
This doesn't make sense as an angle measurement, so there must be an error in the problem. Therefore, we cannot determine the value of the missing angle.
To find the value of the missing angle, we can use the fact that the sum of the interior angles of a triangle is always 180 degrees.
Given that we have three angles provided: 720, 120, and 128 degrees, we can add them together to find the sum of the known angles: 720 + 120 + 128 = 968 degrees.
We know that the sum of the interior angles of a triangle is 180 degrees, so to find the value of the missing angle, we subtract the sum of the known angles from 180 degrees: 180 - 968 = -788 degrees.
Since -788 degrees is not a valid angle measurement, it seems there may be an error in the provided values. Please double check the given angles.
