Answer:

$5.2\:\mathrm{in}$

Step-by-step explanation:

We can set up the following proportion and solve for length ( $\ell$ ):

$\frac{2}{5}=\frac{\ell}{13},\\\\\ell=\frac{2\cdot 13}{5}=\frac{26}{5}=\boxed{5.2\:\mathrm{in}}$

Find m∠ABC = 7x - 4 and m∠BDC = 9x - 1 and and m∠ABC = 107°, find x, m∠ABC and m∠BDC.

Artyom0805 [142]

Answer:

m<BDC = 62 degrees

Step-by-step explanation:

Using the expression;

<ABC = <ABD + <DBC

107 = 7x-4 + 9x - 1

107 = 16x-5

16x = 107 + 5

16x = 112

x = 112/16

x = 7

Get m<DBC

m<BDC = 9x - 1

m<BDC = 9(7)-1

m<BDC = 63 - 1

m<BDC = 62 degrees

Given a standard day, at what altitude is the true airspeed of an aircraft approximately twice of what the airspeed indicator re

Yakvenalex [24]

Answer:

40000ftMSL

Step-by-step explanation:

We know that airspeed is measured using a pilot tube

And the air pressure is a function of density given as

Pressure= 1/2 xdensityx V²

So at 40,000ftMSL

Is this is replaced for V in the equation then the density of air will be 1/4 that of sea level

So since we are deriving velocity from pressure and pressure is 1/4 so the velocity Will be half of its pressure since velocity is squared from The equation above
