Triangle WXY has the interior and exterior angles shown below.

shepuryov [24]

Answer:

The correct option is last one 77 degrees.

Therefore the measure angle W is 77 degrees.

Step-by-step explanation:

Given:

Exterior angle = 122°

∠W = (2x-13)°

∠Y= x°

To Find:

∠W = (2x-13)° = ?

Solution:

Exterior Angle Property:

An exterior angle of a triangle is equal to the sum of the opposite interior angles.

Angle W and Angle Y are the interior angles of Exterior angle 122°.

∴ $Exterior\ angle=m\angle W+m\angle Y$

Substituting the values we get

$122=2x-13+x\\3x=135\\\\x=\dfrac{135}{3}=45\\\\x=45$

Now Substitute 'x' in angle W we get

$m\angle W=2\times 45 -13=77\°$

Therefore the measure angle W is 77 degrees.

The pilot of a Coast Guard patrol aircraft on a search mission had just spotted a disabled fishing trawler and decided to go in

Svetllana [295]

Answer:

$\frac{dD}{dt}= 181\frac{168}{1600}$

Step-by-step explanation:

h= 1000 ft

dx/dt= 232 ft/sec

D= 1600 ft

First, we have to find a distance x ( shown in the figure)

applying pythagorus theorem

D^2= h^2+x^2................1

x^2= D^2-h^2

= 1600^2-1000^2

x^2= 1560000

x=1248.99 m

Now we can find out how fast the aircraft is receding from the trawler

( notice that the height is not changing)

so differentiating equation 1 w.r.t t we get

$\frac{d}{dt} (D^2)= \frac{d}{dt}(h^2+x^2)$

2DD'= 2hh'+2xx'

$D\frac{dD}{dt}= h\frac{dh}{dt}+x\frac{dx}{dt}$

now putting values we get

$1600\frac{dD}{dt}= 1000\times0+232\times1249$

$\frac{dD}{dt}= 181\frac{168}{1600}$

A and b are natural numbers. The diameter of cell a is 2.3 , and the diameter of cell b is 2.3 .

Pani-rosa [81]

After clarification we see the respective diameters are

$A = 2.3 \times 10^{-a}$

$B = 2.3 \times 10^{-b}$

We're asked about the ratio

$A:B = 2.3 \times 10^{-a} : 2.3 \times 10^{-b} = 10^{-a} : 10^{-b} = 10^b : 10^a = 10^{b-a} : 1$

Now we can go through the choices.

A. If a = 4 and b = 6, then cell a is 100 times greater than cell b.

$A:B=10^{6-4}:1 = 100:1$

It would be more proper to say the diameter of cell A is 100 times the diameter of cell B, but yes, this is TRUE.

B. If a = 4 and b = 6, then cell b is 100 times greater than cell a.

FALSE. 10 to the minus 4 is 100 times bigger than 10 to the minus 6, so a is bigger.

C. If a = 4 and b = 6, then cell a is 2 times greater than cell b.

FALSE. We already calculated its 100 times bigger.

D. If a = 4 and b = 6, then cell b is 2 times greater than cell a.

FALSE.
