Answer:
B) 8n+4
Step-by-step explanation:
The product of 8 and n means 8n. Four more means +4. These together equal B) 8n+4
You could do -1/-2 times -5/-4 which would be 5/8
Distance of A from cliff = 1500·arctan(30°) ≅ 723.5 ft
distance of B from cliff = 723.5+1000√3 ≅ 2455.6 ft
tanθ = 2455.6/1500 = 1.637
θ = arctan(1.637) ≅ 58.6°
angle of depression = 90-θ ≅ 30°
