To find the measure of the second angle, we can use the fact that the sum of the measures of two angles that add up to 180° is 180°.
So we have (2x + 20) + (C) = 180°, where (2x + 20) is the first angle and C is the measure of the second angle.
To solve for C, we can simplify the equation and solve for C:
2x + 20 + C = 180
2x + C = 180 - 20
C = 160 - 2x
Therefore, the measure of the second angle is 160 - 2x.
