Answer:
x = 4
Step-by-step explanation:
Using the sine ratio on right triangle KJL
and the exact value sin30° = 
sin30° =
=
=
=
( cross- multiply )
2JL = 8
( divide both sides by 2 )
JL = 4

Using the sine ratio in right triangle JLM
and the exact value sin45° = 
sin45° =
=
=
=
( cross- multiply )
x ×
= 4
( divide both sides by 
x = 4
The answer is A. 2x^2+11x^3+12x^2-10x-8
