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:
Area of the rectangle is 10x²+7-6
Step-by-step explanation:
Area of rectangle is the product of its length and width
As length of given rectangle is 5x+6 and its width is 2x-3 the are is
(5x+3)(2x-3)
=5x·2x-5x+6·2x-6
=10x²-5x+12x-6
=10x²+7x-6
