Answer:
16.2
Step-by-step explanation:
Since, if the sum of two angles is 90° then they are called complementary angles.
Here, the given angle is 73.8°,
Let x be the complementary angle of 73.8°,
Thus by the above definition,
x + 73.8° = 90°,
By subtraction property of equality,
⇒ x = 16.2°,
Hence, the complementary angle of 73.8° is 16.2°.
