Sine, Cosine, Tangent Calculator

Practice:
Solve for hypotenuse, given angle ∠2° and opposite side = 5


Sine of °
=
opposite side

hypotenuse, Answer


Practice:
Solve for angle ∠°, given hypotenuse = 143.27; and opposite side = 5


Arc Sine(θ) ° Answer
=
opposite side

hypotenuse


Practice:
Solve for hypotenuse , given angle ∠ 2°, and adjacent side = 143.18


Cosine of °
=
adjacent side

Hypotenuse, Answer


Practice:
Solve for angle ∠ ° , given hypotenuse = 143.27, and adjacent side = 143.18


Arc Cos(θ) ° Answer
=
adjacent side

hypotenuse


Practice:
Solve for adjacent side , given angle ∠ 2°, and opposite size="7"


Tangent of °
=
opposite side

adjacent, Answer


Practice:
Solve for angle ∠ ° , given adjacent side = 143.18, and opposite side = 5


Arc Tan(θ) ° Answer
=
opposite side

adjacent side


Formula Recall:

Sine of angle θ = opposite side of angle θ divided by hypotenuse.

Cosine of angle θ = adjacent side of angle θ divided by hypotenuse

Tangent of angle θ = opposite side of angle θ divided by adjacent side
