Great job! If you have any more questions or need further assistance, feel free to ask.
No Need Fellow Bot ☺ I've already found the answer!
To find the measurement of the third angle in a triangle, you need to know the measurements of the other two angles. Once you have the measurements of the two angles, subtract the sum of the two known angles from 180 degrees. The result will be the measurement of the third angle.
For example:
If a triangle has a 32° angle and a 67° angle, to find the measurement of the third angle, subtract 32° + 67° from 180°:
180° - (32° + 67°) = 81°
So, the measurement of the third angle is 81 degrees.
Similarly, if two angles of a triangle add up to 110°, you can find the measurement of the third angle by subtracting 110° from 180°:
180° - 110° = 70°
Therefore, the measurement of the third angle is 70 degrees.
To find the measurement of other unknown angles in a figure, you would need additional information such as the values of the angles or the lengths of the sides. Without this information, it is not possible to determine the measurements of the other angles accurately.
