sin, cos, and tan | sin θ = opposite / hypotenuse cos θ = adjacent / hypotenuse tan θ = opposite / adjacent |

Law of sines | a/sin A = b/sin B = c/sin C Here, A, B, and C are the angles of a triangle and a, b, and c are their respective opposite sides. |

## How do you find an angle using cosine?

**Example**

- Step 1 The two sides we know are Adjacent (6,750) and Hypotenuse (8,100).
- Step 2 SOHCAHTOA tells us we must use Cosine.
- Step 3 Calculate Adjacent / Hypotenuse = 6,750/8,100 = 0.8333.
- Step 4 Find the angle from your calculator using cos
^{–}^{1}of 0.8333:

## How do you find a missing angle?

## How do you find an angle with 3 sides?

## How do you convert COS to degrees?

## How do you find the angle using sine cosine and tangent?

**In any right angled triangle, for any angle:**

- The sine of the angle = the length of the opposite side. the length of the hypotenuse.
- The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.
- The tangent of the angle = the length of the opposite side. the length of the adjacent side.

## Can you solve a triangle with 3 angles?

We must use The

**Law of Cosines**first to find any one of the three angles, then we can use The Law of Sines (or use The Law of Cosines again) to find a second angle, and finally Angles of a Triangle to find the third angle.## How do you find an angle with two sides?

## How do you find the angle of a right triangle?

**How to find the angle of a right triangle**

- sin(α) = a / c so α = arcsin(a / c) (inverse sine)
- cos(α) = b / c so α = arccos(b / c) (inverse cosine)
- tan(α) = a / b so α = arctan(a / b) (inverse tangent)
- cot(α) = b / a so α = arccot(b / a) (inverse cotangent)

## How do you solve for unknown angles?

## What is SSS math?

SSS (side-side-side)

**All three corresponding sides are congruent**. SAS (side-angle-side) Two sides and the angle between them are congruent.
