Answer:

C. 45 degree angle

Step-by-step explanation:

let AB be the height of the wall and CD be the height of boy

with BC as distance between them.

we have AE = AB-BE = 3.64-1.54 = 2.1m

and ED = BC = 2.1m

in triangle AED, we have

tanФ = P/B = 2.1/2.1

tanФ = 1

∴ Ф = 45°

Hence the sun is elevated at an angle of 45 °.
