# An angle is two-thirds of its supplementary angle. Find the angle.

##### SOLUTION
Let the angle be $\theta$.
$\therefore$    $\theta =\dfrac { 2 }{ 3 } \left( 180-\theta \right)$
$\Rightarrow 3\theta =360-2\theta$
$\Rightarrow 5\theta =360\Rightarrow \theta ={ 72 }^{ 0 }$

Q5 Subjective Medium
Read the following two statements which are taken as axioms:
(i) If two lines intersect each other, then the vertically opposite angles are not equal.
(ii) If a ray stands on a line, then the sum of two adjacent angles so formed is equal to $180^0$.
Is this system of axioms consistent? Justify your answer.
