Answer:
68.17m
Step-by-step explanation:
Please see attached a rough sketch of the scenario
Step one:
Given data
Height of victim= 4.5ft
The horizontal distance of the snipper from the building = 780ft
The angle of elevation= 5 degrees
Required
The vertical distance
The opposite= the vertical distance
789 ft = the adjacent
Step two:
Applying SOH CAH TOA
tan ∅= opp/adj
tan 5= opp/780
cross multiply we have
0.0874= opp/780
cross multiply we have
0.0874*780= opp
opp= 68.17m
The sniper shoots from a vertical distance of 68.17m
Answer:
16.9°
Step-by-step explanation:
tan x = 1.7/5.6
tan^-1 x = 16.9°
I just gave you the answers
Answer:
D
Step-by-step explanation:
-4(-2)^2 -3(-2) +2
-4(4) +6+2
-16+8
-8
Circumference = 2πr = 2π(1.25) = 7.85ft
I hope this answers your question and best of wishes!!
