Find x in triangle
Exterior is 120 degrees and 20 degrees
Find interior x
180 degrees total
To find the value of x in the triangle, we will subtract the given exterior angles from 180 degrees (total interior angle).
1. Start with the total interior angle of a triangle: 180 degrees.
2. Subtract the first given exterior angle from the total: 180 degrees - 120 degrees = 60 degrees.
3. Subtract the second given exterior angle from the previous result: 60 degrees - 20 degrees = 40 degrees.
Therefore, the value of the interior angle x in the triangle is 40 degrees.
