Answer:

The distance between B and lighthouse is 3.8688 km

Step-by-step explanation:

Given:

The angle made from ship to lighthouse is 36.5 degrees

and that of point B is 73 degrees.

To Find:

Distance Between Point B and Lighthouse

Solution:

<em>Consider a triangle LAB(Refer the attachment )</em>

And Point C is on the line AB as A i.e. ship is sailing to B

So C is at 5 km from A.

Now In triangle LAC,

Using Trigonometry Functions as ,

tan(36.5)=LC/AC

LC=tan(36.5)*AC

=0.7399*5

=3.6998 km

Now In triangle LBC,

As,

Sin(73)=LC/LB

LB=LC/(Sin(73))

=3.6998/0.9563

=3.8688 km

LB=3.8688 km

Find the value of x!!

Lyrx [107]

Answer:

x = 6

Step-by-step explanation:

These two angles make a complementary angle meaning the sum of the angles will be 90°. We can use this information to make an equation to solve for x.

10x + 30 = 90 (Given)

10x = 60 (Subtract 30 on both sides)

x = 6 (Divide 10 on both sides)

If UV ≅ UX and WX=23, what is VW?<br><br> VW =

KiRa [710]

<h2>Answer: </h2>

The length of VW is 23°

<h2>Step-by-step explanation: </h2><h3>Known : </h3>

UV = UX
WX = 23

<h3>Asked : </h3>

VW = ?

<h3>Solution : </h3>

Since the UV line and UX line has the same length, so the VW line should have the same length as the WX line.

VW = WX

23 = 23

<h3>Conclusion : </h3>

The length of VW is 23°

using the point-slope formula, what is the equation of the line that passes through the points (1, 5) and (0, 0)? a. y = x b. y

Dmitry_Shevchenko [17]

First we find the slope m as follows:
$m=\frac{y-y_{1}}{x-x_{1}}=\frac{5-0}{1-0}=5$
So the equation is of the form:
y = 5x + b
When x = 1, y = 5. Therefore b = 0.
So the equation is:
y = 5x
