17c-10=4 ............................
1 answer:
Answer:
1.214 or or
Step-by-step explanation:
To solve this equation, first you need to the variable term isolated. You do this by adding 10 to each side. Your equation will now look like
17c = 14
Next, you will divide both sides by the 17.
Your equation now is solved, and above, I put ther three different forms for your answer: decimal, mixed number, and improper fraction.

We know that
The arrangement forms an isosceles triangle with equal legs of 8 miles.
The angle between the legs is equal to
°
Therefore, the other two angles are
Angles = (180-60)/2 = 120/2 = 60°
It can, therefore, be noted that all angles are equal and thus the resulting triangle is actually an equilateral triangle and thus all the sides are equal.
Hence
the answer is
the distance between the two ships is 8 miles apart
alternative Method
Applying the law of cosines
<span>c²=a²+b²-2*a*b*cos C
</span>where
a=8 miles
b=8 miles
C is the angle between the legs-------> 123-63------> 60 degrees
c is the distance between the two ships
so
c²=8²+8²-2*8*8*cos 60------> c²=64-------> c=√64------> c=8 miles
