Question

Find the angle which is half of its complement ?

Answer 1

_{Two angles are complementary if their sum is equal to 90 degrees.}

_{Let x be the angle, then its complementary angle is 90-x . We are told that the angle is half of itz complement, so}

_{$x=\frac{1}{2}(90-x)$ multiply by 2}

_{2x=90-x move x to left side}

_{3x=90 divide by 3}

_x=30

_{The angle is 30 degrees.}
