Please explain the answer if anyone knows.

No ^ terms mean the answer is to be in *a* degree, by only looking at options.
Let's assume L*a=h like in h^2/2L.
This gives in terms of a^2.
Let's assume L*a=h like in h^2/2L.

= h^2/2*l
= (l sina)^2/2*l.
= l*a^2/2 [in radian converting to degree i.e. (pi/180)^2].
= 0.00015*l*a^2.
= 1.5/100*a^2.
= (l sina)^2/2*l.
= l*a^2/2 [in radian converting to degree i.e. (pi/180)^2].
= 0.00015*l*a^2.
= 1.5/100*a^2.
