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
Answer:
I think the answer would be 3 minutes 32 seconds. I hope this helps.
The scale factor is 1/22.
In the drawing, the height of the school shows 1.6 feet.
In order for us to know the actual height, we can have it as.
1.6 = Height of school * (1/22)
1.6 = Height of school / 22
Height of school = 35.2
So the actual height of the school is 35.2 feet.
