The complete question is missing, so i have attached it.
Answer:
x = 9(sin 42)/(sin 29)
Step-by-step explanation:
We want to find an expression for x.
From the attached image, we can see a triangle with 2 angles given and 2 sides to be 9 and x respectively.
Now, the law of sines says that;
A/sin A = B/sinB = C/sin C
So applying it to this question, we have;
x/sin 42 = 9/sin 29
Thus,
x = 9(sin 42)/(sin 29)
