Answer:
the complementary angle of 49.2° is 40.8⁰
Explanation:
Given;
measure of the angle = 49.2°
Let the complementary angle be x
Complementary angles sum up to 90 degrees.
The value of x is calculated as follows;
x + 49.2° = 90⁰
x = 90⁰ - 49.2°
x = 40.8⁰
Therefore, the complementary angle of 49.2° is 40.8⁰.
