The angle of B is 
Explanation:
It is given that 
and 
To determine the 
, let us use the law of sine formula.
Thus, we have,
Substituting the values in the formula, we have,
Multiplying both sides by 3,we get,
Simplifying and dividing, we get,
Multiplying both sides by 
, we get,
Thus, 
Hence, The angle of B is
Answer:
First figure out how many cups are in a gallon. 16 .
Next multiply 16×3= 48
Finally you divide price per cup or 20.16/ 48.
The cost is .42 cents per cup.
The answer to this is 99.
You take all known values and subtract it from 360.
360-132-39-90=99.
Answer:
I'm pretty sure the answer is A.
Answer
<em>length = width + 15</em>
<em>Area = length * width; area is 54 square feet.</em>
<em>Two equations are:</em>
<em>L = W + 15</em>
<em>L * W = 54</em>
<em>To solve, we substitute first equation into second equation:</em>
<em>(W + 15) * W = 54</em>
<em>w^2 + 15w = 54</em>
<em>w^2 + 15w - 54 = 0</em>
<em>(w+18)(w-3) = 0</em>
<em>w = -18 or 3</em>
<em>The width cannot be negative, so 3 is the width and since length is 15 more than width, length is 18:</em>
<em />
<em>Length = 18 feet</em>
<em>Width = 3 feet</em>
<em />
