an angle is double than its complement.what is its measure?explain.

Let the required angle = *x*^{0}

then measure of its complement = ( 90 - *x* )^{0}

according to the given condition,

*x* = 2 ( 90 - *x *)

⇒ *x *= 180 - 2*x*

⇒ *x* + 2*x* = 180

⇒ 3*x *= 180 ⇒ *x* = 60

so, the measure of required angle = **60**^{0}
