Answer:
51.23
Step-by-step explanation:
The answer is number 1 according to my math in my head right now
Ratio of areas of similar triangles is 9 : 25.
Solution:
Given data:
Ratio of sides of two similar triangles = 3 : 5
To find the ratio of areas of the triangles:
We know that,
<em>In two triangles are similar, then the ratio of their area is equal to the square of the ratio of their sides.</em>
Ratio of areas of similar triangles is 9 : 25.
We know that
[the component East (x axis)]=16+18*cos 55°---------> 26.32 miles
[the component North (y axis)]=18*sin 55°--------------> 14.74 miles
<span>applying the Pythagorean theorem we can know the distance from the harbor
</span>d²=26.32²+14.74²---------> d²=910.01--------> d=√910.01--------> d=30.17 miles
the answer is
30 miles
