How to find angles:
Where:
- θ\theta is the angle.
- “Opposite” is the side opposite to the angle.
- “Hypotenuse” is the longest side of the triangle.
To find the angle:
θ=sin−1
Use the inverse sine (sin⁻¹) to calculate the angle.
Using Cosine (cos):
cos(θ)=
Where:
- “Adjacent” is the side next to the angle.
- “Hypotenuse” is the longest side of the triangle.
Use the inverse cosine (cos⁻¹) to find the angle.
θ=cos−1
Using Tangent (tan):
tan(θ)=
- “Opposite” is the side opposite the angle.
- “Adjacent” is the side next to the angle.
To find the angle:
θ=tan−1
