So to rewrite it so that we can find the side, we just need to isolate the a variable.

So firstly, divide by 6 on both sides of the equation: 
Next, square root each side, and your answer should be 
Answer:
18
Step-by-step explanation:
Let <span>sin(90° - )------------------------ > sin (90-x)
</span>sin(a - b<span>) = sin a*cos b - cos a*sin b
</span><span>so
</span>sin(90 - x) = sin 90*cos x - cos 90 * sin x
sin(90 - x) = 1*cos x - 0* sin x-------- > cos x
the answer is the option <span>D. cos()</span><span>
</span>
Answer:
1. A 2. B
Step-by-step explanation:
1. 9(6 times x) and 9 x 6 + 9 times x
Thhis is correct because you do the same for both
2. 1 pound is 16 ounces. So 12.5 x 16 = 200
