Answer:
x ≈ 8.0
y ≈ 6.0
Step-by-step explanation:
For x, the relevant trig relation is ..
Sin = Opposite/Hypotenuse
sin(53°) = x/10
x = 10·sin(53°)
x ≈ 8.0
__
The value of y can be found in the same way using the 37° angle, or the cosine function can be used.
y = 10·sin(37°) ≈ 6.0
y = 10·cos(53°) ≈ 6.0

<em>Additional comment</em>
This question only asks for the value of x. We expect there may be some versions of this question in which the value of y is requested, or in which the positions of x and y are switched. Please compare your question carefully before you copy the answer.

You may notice this is a 3-4-5 triangle with a scale factor of 2.
Set 7x-4 and 31 equal to each other
7X-4=31
Add four to both sides
7X=27
X=3
The answer is D
