Question

define trigonometric function
2 define angle of elevation
​

Answer 1

Answer:

heya ❤️

Step-by-step explanation:

Angles of elevation and depression. If a person stands and looks up at an object, the angle of elevation is the angle between the horizontal line of sight and the object. If a person stands and looks down at an object, the angle of depression is the angle between the horizontal line of sight and the object.

Answer 2

$\red{ \mathtt{→Trigonometric \ Function:}}$

• The trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.

• They are widely used in all sciences that are related to geometry, such as navigation, solid mechanics, celestial mechanics, geodesy, and many others.

$\red{ \mathtt{→Angle \ of \ Elevation:}}$

• The "upwards" angle from the horizontal to a line of sight from the observer to some point of interest.

$\red{ \mathtt{→Examples:}}$

• From a boat on the lake, the angle of elevation to the top of the cliff is 24°22'. If the base of the cliff is 747 feet from the boat, how high is the cliff (to the nearest foot)?

• From a boat on the river below a dam, the angle of elevation to the top of the dam is 24°8'.
