Mathematics

Write the complement (in degree) of each of the following angles: $$77^{\circ}$$


ANSWER

13


SOLUTION
As we know for becoming a complementary angle the sum of both the angles should be $$90^{\circ}$$

Let the complementary angle be $$x$$

$$77^{\circ}+x=90^{\circ}$$
$$\Rightarrow x=13^{\circ}$$

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.
