Question

Question 1
The angles between North and West and South and East are
(a) complementary
(b) supplementary
(c) both are acute
(d) both are obtuse

Answer 1

From the above figure, it is clear that the angle between North and West and West is ${90}^{\circ }$ and South and East is ${90}^{\circ }$.
$\therefore$ Sum of these two angles $={90}^{\circ }+{90}^{\circ }={180}^{\circ }$.
Hence, the two angles are supplementary, as their sum is ${180}^{\circ }$
