Answer:

28.246

Step-by-step explanation:

hihi. So you can use the Pythagorean theorem to find any missing sides to a triangle. The equation goes like this: a^2 + b^2 = c^2, where a a and b are the lengths of the 2 bases of the triangle and c is the length of the hypothenuse/longest side to the triangle. Since you know the length of the hypothenuse and of one of the bases you can solve for the last base using the equation which gets you ~8.246. Now, adding that to the other side lengths gets you 28.246 as an approximate perimeter to 3 sig figs

Answer:

The distance of the ship from the cliff is 38.465 feet

The height of the cliff is 46.28 feet.

Step-by-step explanation:

As shown in the figure attached $d$ is the distance from the ship to the cliff, and $h$ is the height of the cliff from the ship.

From trigonometry

$tan(20^o)=\frac{14}{d}$

$d=\frac{14}{tan(20^o)}=38.465\:feet.\\\\\boxed{d=38.465ft}$

This is the distance to the cliff.

And we have

$tan(40^o)=\frac{h}{d}$

since $d=38.465ft$

$h=d*tan(40^o)=38.465*tan(40^o)=32.28ft$

Ad the height of the cliff is just $14+h$ or

$32.28+14=46.28 ft\\\\\boxed{height=46.28ft}$

Which is the height of the cliff.
