C-08-Q223mediumsingle_mcq

In the sample MCQ, with centre $O$ and the given figure, the angle $x$ on the circumference standing on a central angle of $108^{\circ}$ is—

a $126^{\circ}$
b $108^{\circ}$
c $72^{\circ}$
d $54^{\circ}$

ব্যাখ্যা

The angle subtended by an arc at the centre is twice the angle it subtends at any point on the remaining circumference. Therefore $x = \tfrac{1}{2}\times 108^{\circ} = 54^{\circ}$ .
