# The moon is observed from two diametrically opposite points A and Bon Earth. The angle $\theta$ subtended at the moon by the two directions of observation is $1^{\circ}54'$. Given the diameter of the Earth to be about $1.276 \times 10^7 m$. Compute the distance of the moon from the Earth.

$\begin {array} {1 1} (A)\;38.4 \times 10^8m & \quad (B)\;38.4 \times 10^4m \\ (C)\;3.84 \times 10^8m & \quad (D)\;3.84 \times 10^4m \end {array}$

$3.84 \times 10^8m$
