Answer: m∠P ≈ 46,42°

because using the law of sines in ΔPQR

=> sin 75°/ 4 = sin P/3

so ur friend is wrong due to confusion between edges

+) we have: sin 75°/4 = sin P/3

=> sin P = sin 75°/4 . 3 = (3√6 + 3√2)/16

=> m∠P ≈ 46,42°

If you make multiple measurements of your height, you are likely to find that the results vary by nearly half an inch in either

Lisa [10]

Answer:

Height h= 1.7 m

Explanation:

Supposing we have to find height in meter.

1 feet = 0.3048 m

1 inch = 0.0254 m

Given that:

5 feet

= 5×0.3048

= 1.524 m

and 7 inch = 7×0.0254= 0.1778 m

Therefore total height of a man in meter

5 feet 7 inch = 1.5424+0.1778 =1.7 m

Height h= 1.7 m

Explanation:

Here it is given 

Work (W) = 3560 J

Time (t) = 55 sec

power (P) = ?

We know we have the formula 

 $p = \frac{w}{t}$ 

P = 3560/55

P = 64.73 watt

when the elevator is moving upwards but its slowing to a stop at the top floor. what is the direction of the net force on the ri

Zielflug [23.3K]

Answer:Downward

Explanation:

As elevator is moving upward but is decelerating to stop at top

Suppose mg is the weight of man

N is the normal reaction

a is the acceleration

$F_{net}=N-mg=m(-a)$

here upward direction is positive while downward direction is negative

Therefore net force is in downward direction
