Answer:

6.2 units

Explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relations between trig functions and sides of a right triangle.

Common segment

To find the value of x in this figure, we need to know the length of the common segment between the two triangles. That segment is opposite the 53° angle, so can be found using the sine relation:

Sin = Opposite/Hypotenuse

Opposite = Hypotenuse × Sin = 30·sin(53°) ≈ 23.9591

__

Missing measure

The side marked x is adjacent to the marked angle in that triangle, so the relevant relation is ...

Cos = Adjacent/Hypotenuse

Adjacent = Hypotenuse × Cos = 23.9591·cos(75°) ≈ 6.20106

The length of the side marked x is about 6.2 units.
