From the law of sines, we have:

,
where x and y are the sides opposite to angles X and Y, respectively.
Substituting the known values, we have:

, thus

.
Using a calculator, we can find that arcsin(0.31)=18 degrees, approximately.
We know that sine of (180-18)=162 degrees is also 0.31. But 162 and 51 degrees add up to more than 180 degrees.
Thus, there is only one triangle that can be formed under these conditions.
The question is an illustration of a division model.
The boxes will be completed with: 1650, 231, 50 and 7
The expression is represented as:

Express 1881 as 1650 + 231.

<span>y=2(1/2)^x
</span>
x = 0; <span>y=2(1/2)^0 = 2(1) = 2
x = 1; </span><span>y=2(1/2)^1 = 2(1/2) = 1
answer is the last one.</span>
The answer is 24d^2-62d+35
