We have a triangle where.
a=adjacent leg of A=30 ft
A=90º-(angle of depression)=90º-10º=80º
b=distance between the base of the lighthouse and the ship
tan A= opposite /adjacent.
tan 80º=b /30 ft  ⇒b=(30 ft)(tan 80º)≈170.14 ft

Answer: the distance would be 170.14 ft

Step-by-step explanation:

Since this is a right triangle and we are given an angle measure that measure 45, the other angle measure also measure 45.

So this means we are dealing with a 45-45-90 triangle.

A 45-45-90 triangle legs are equal to each other and the hypotenuse measures sqr root of 2 times more than the legs.

The hypotenuse measure 2 times sqr root of 14 so divide by sqr root of 2 to find x and y.

\frac{2 \sqrt{14} }{1}  \times   \frac{1}{ \sqrt{2 } }  =  \frac{ \sqrt{56} }{ \sqrt{2} }  =  \sqrt{28}  = 2 \sqrt{7}

Since x and y are equal, they both measure

2 \sqrt{7}
