Mathematics

Mark the correct alternative of the following.In figure, the value of x is?

$22$

SOLUTION
Now,
$(8x-41)^o+(3x)^o+(4x-5)^o+(3x+10)^o=360^o$ [ Since sum of all angles is $360^o$]
or, $8x^o+3x^o+4x^o+3x^o-46^o+10^o=360^o$
or, $18x^o-36^o=360^o$
or, $18x^o=396^o$
or, $x=22$.

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.
