Answer:
63.4°
Step-by-step explanation:
Pole height = 1
shadow = 1/2
tan ∠CAB = 1 / (1/2) = 2
∠CAB = 63.4°
For Geometric sequence, the next term is multiplied by the common ratio.
Common ratio, r = 1/4
1st term, a = 96
2nd term = ar = 96*1/4 = 24
3rd term = ar² = 96*(1/4)*(1/4) = 6
Sum of the first three terms = 96 + 24 + 6 = 126
