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:
the answer is 4
Step-by-step explanation:
my step by step explanation is that whatever i say is right so i could probably say that it is 5 and still get it right just bc i said it
3(2x - 1) - 2(3x + 4) = 11x
- Distribute 3 inside the parentheses.
6x - 3 - 2(3x + 4) = 11x
- Distribute 2 inside the parentheses.
6x - 3 - 6x - 8 = 11x
-11 = 11x
<h3>x = -1</h3>
Answer:
p : q : r = 10 : 4 : 3
Step-by-step explanation:
Expressing the ratio in fractional form
= 
( cross- multiply )
4r = 3q ( divide both sides by 4 )
r = 
q = × 2 = 
Then
p : q : r
= 5 : 2 : ( multiply all parts by 2 )
= 10 : 4 : 3
