Answer:
71
Explanation:
a complementary angle is the sum of 2 angles that equals 90. So if one angle is 19 degrees then 19- 90 = 71 so the other angle measure is 71
71 degrees
If the angles are complementary, they add up to 90. Let x be the angle we are trying to find the measure of:
x+19=90
Subtract 19 from both sides
x=71
