Complementary angle of $$72\displaystyle \frac{1}{2}^{\circ}$$ is:


ANSWER

$$17\displaystyle \frac{1}{2}^{\circ}$$


SOLUTION
Given angle is $$72.5^{\circ}\text{ or }\ 72\dfrac{1}{2}^{\circ}$$
Let the other angle $$=x$$
Sum of complementary angles $$= 90^{\circ}$$
$$\Rightarrow x+72\dfrac{1}{2}^{\circ}=90^{\circ}$$
$$\Rightarrow x=17\dfrac{1}{2}^{\circ}$$
