Kristin is swimming in the ocean and notices a coral reef below her. the angle of depression is 35∘ and the depth of the ocean, at that point is 250 feet. how far away is she from the reef? round your answer to the nearest tenth of a foot if necessary.

Distance: 435.9 ft

Step-by-step explanation:

This is a right triangle shown in the picture.

To solve for , we can use trigonometry.

The 35° angle's opposite side is 250 ft and the hypotenuse of the triangle is (what we are seeking to find).

The ratio that relates opposite and hypotenuse is sine.

We know that,

Thus we can write:

Cross multiplying and solving for gives us:

Second answer choice is right: 435.9 ft

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000

i think is g(1)=-1.

hope that i can
