As given in the problem, the distance from the moon and the earth is 60 radius.
For example assume, that the angle to be θ, now
tan θ = R/d
= R/60R
=1/60
=0.016 θ
= tan−1(0.016)
θ = 0.90
Therefore, for calculating the diameter, the angle becomes 2 times of θ therefore
2 θ = 2x 0.90 = 1.80
Thus, 1.8 degree is the approx value for diameter of earth.
