Question

* Example 1.3: The moon is at a distance o
3.84x108 m from the Earth. If viewed from tw
diametrically opposite points on the Earth, th
angle subtended at the moon is 1° 54'. What i
the diameter of the Earth?​

Answer 1

Explanation:

tan (1° 54' ) = p/b

which means that, p = b * (tan 1° 54' )

= 384x108 *0.033

= 13757 km
