The tangent of angle J

The angle above horizontal that an observer must look to see an object that is higher

than the observer.

The angle below horizontal that an observer must look to

see an object that is lower than the observer.

The relationship between the angle of elevation

and the angle of depression.

Complementary angles must always be

__________.

The angle congruent to the angle of elevation.

Two angles whose sum is 90 degrees.

The complement of sin 300

.

The complement of cos 440

.

Kristin is swimming in the ocean and notices a coral reef below her. The angle of depression is 350 and the depth of the ocean, at that point is 250 feet.

This measurement is represented by x.

The trig equation needed to find the height of the building.

Insanity, atop the Stratosphere in Las Vegas, tilts riders at an angle of 700 from the vertical. Riders can see the Las Vegas Strip 900 feet below. The arms of the ride measure 40 ft.

This measure is the distance the riders are from the vertical.

The value of x.

The distance, d, from the ship to the shore.
