Find the supplement of the angle :
$$\dfrac{2}{5}$$ of a right angle


ANSWER

$$144$$


SOLUTION
Two angles are supplementary if their sum is $$180^0$$.
If one angle is $$\dfrac {2}{5}$$ of a right angle, then other angle is $$180-\left(\dfrac {2}{5}\times 90\right)=180-(2\times 18)=180-36=144^0$$.
