Question

If 7x + 27o and 4x – 14o are complementary angles, what is the value of x?
note : o is degrees

Answer 1

Answer:

7x + 27° and 4x - 14° are complementary angles

So their sum is 90°

By the problem ,

7x + 27° + 4x - 14° = 90°

or, 11x + 13° = 90°

or, 11x = 90° - 13°

or, 11x = 77°

or, x = 7°
