I need to know which side the 4 is (the short leg opposite 30°, the long leg opposite 60°, or the hypotenuse). For a 30°–60°–90° triangle the side ratios are 1 : √3 : 2 (short : long : hypotenuse). Here are the possible values of x (rounded to the nearest tenth) depending on where the 4 sits:

- If 4 is the short side (opposite 30°):
- long side x = 4√3 ≈ 6.9
- hypotenuse = 8

- If 4 is the long side (opposite 60°):
- short side x = 4/√3 ≈ 2.3
- hypotenuse = 8/√3 ≈ 4.6

- If 4 is the hypotenuse:
- short side x = 2.0
- long side = 2√3 ≈ 3.5

Tell me which side is labeled 4 (or upload the diagram) and I’ll give the single correct value for x.
