Right Triangle Trigonometry

formula: tan y = opposite/adjacent

= Is a angle formed by a horizontal line
and a line of sight to a point below the line.

Usually an angle of depression is
less than or equal to 90°.

= Triangle measurements.

Used to calculate lengths of
side and measures of angles
in a triangle.

How to solve =

locate the degree of angle A , while given the alternative side and hypotenuse. From perspective A , the sides opposite and hypotenuse are given. consequently, use the sine trigonometric characteristic. (Soh from Soh Cah Toa)
Write the equation and remedy using the inverse key for sine.

SOH CAH TOA

Sin = opp/hyp

Sin = Sine

cos = adj/hyp

Cos = Cosine

Tan(a) = opp/hyp

Tan = Tangent

Formula = a2 + b2 = c2

hypotenuse= Longest side.

Adjacent= Oppostie from the hypotenuse.

Opposite= the opposite side from a angle.
