• [Right Triangles Only] SOHCAHTOA
• [Right Triangles Only] tan∅ = opposite over adjacent

Explanation:

Step 1: Define

We have a right triangle triangle. We can use trig to find the missing length.

Step 2: Identify Variables

POV from the angle measure

Angle = 64°

Opposite = 13

Adjacent = x

Step 3: Solve for x

1. Substitute: tan64° = 13/x
2. Multiply x on both sides: xtan64° = 13
3. Isolate x: x = 13/tan64°
4. Evaluate: x = 6.34052
