Question
The angle which is equal to 8 times its complement is:

Answer

  1. 80º
    Solution:
    We know that two angles, whose sum is 90º, are called the complementary angle.
    Let one angle be x then its complementary angle be 8x,
    x + 8x = 90º
    9x = 90º
    x = 10º
    Its complementary angle is 8 × 10 = 80º.
