Answer:
The measure of its complementary angle is 87°
Explanation:
We know this because the sum of two complementary angles is always equal to 90°, so:
90 - 3 = 87
Therefore, your final answer will be 87°
87°
if an angle is complementary that means that equals 90°.
and we know one part of the angles, so then we take 90° - 3° and we get 87°.
