Answer:

The value of x is 2√2

Explanation:

Use trig (specifically, the sine function) to find the length of JL:

Since sin Ф = opp / hyp, opp = hyp·sin Ф.

Here, opp is the length of JL and is found as follows:

|JL| = 8√2·sin 30° = 8√2·(1/2) = 4√2

Note that this 4√2 is the length of the hypotenuse of the smaller triangle.

Applying the definition of the sine function again:

x = hyp· sin Ф, and with hyp = 4√2 and Ф = 45°, we have:

x = (4√2)(1/2) = 2√2

The value of x is 2√2
