Step-by-step explanation:
Here. ...the sum of interior angle of triangle is 180° so...
90° + 43° + y = 180°.
133° + y = 180°
y = 180° - 133°
y = 47°
Answer:
2236.77 feets
Step-by-step explanation:
From the attached picture, we are to find x, which is the vertical depth of the submarine.
Using trigonometry based on the illustration in the diagram:
Sinθ = opposite / hypotenus
Sinθ = x (depth of submarine) / distance from ship (4000)
Hence,
Sinθ = x / 4000
θ = 34°
Sin34 = x / 4000
0.5591929 * 4000 = x
2236.7716 = x
Hence, depth of submarine = 2236.77 feets
Answer:
True
Step-by-step explanation:
It has a common ratio of -1/2
Each term after the first is obtained by multiplying the previous one by -1/2:-
-1/2 * 1/2 = 1/4 ; 1/4 * -1/2 = -1/8 and so on.
