15/4.
Step-by-step explanation:
4th term = a1 r^3
= 30(1/2)^3
= 30/8
= 15/4.
Answer:
22.77°
Step-by-step explanation:
Using SOH CAH TOA trigonometry identity
Height of the building (opposite side) = 172ft
Length of the shadow (hypotenuse) = 444ft
Using SOH
sin theta = opp/hyp
Sin theta = 172/444
Sin theta = 0.387
theta = arcsin0.387
theta = 22.77°
Hence the angle of depression is 22.77°
The answer would be 314 feet I believe
