If two angles are supplementary, their measures add up to 180 degrees.
Let m1 be the measure of angle 1.
Since angle 1 and angle 2 are supplementary, we can write the equation:
m1 + m2 = 180
Substituting the given value of m2 = 97, we have:
m1 + 97 = 180
Subtracting 97 from both sides, we get:
m1 = 180 - 97
m1 = 83
Therefore, the measure of angle 1 is 83 degrees.
