209 is the answer to you problem hope it helps
Answer:
Step-by-step explanation:
A = 150°
B = 12°
C = 180 - (150 + 12) = 18°
b = 10 cm
Apply the sine rule:

Plug in the values

Multiply both sides by sin(18)


c = 14.9 cm (nearest tenth)
The answer is: "

" ;
or, write as: "
0.63333333333..." ; or, round to: "
0.6333" .

First think of the form a^2 + 2c + c^2
c in the question is clearly 3.
So we need first to add 8 for both sides to get rid of -8 and then add 9 to complete the square.
So it will be (x^2+3)^2 = 17
So the choice number 3 is the answer.
Hope this helps!
