<u><em>We need to solve for the angle VXY and it is equivalent to (18x - 2)°. We all know that the total angle of the given figure is 106°, so by adding the angles of the four sides, we can solve for the value of x. The solution is shown below:</em></u></h3>
<em>∠WVX + ∠VXY + ∠XYW + ∠YWV = 360°</em>
<em>Substituting their values, we have:</em>
<em>90° + (12x + 2)° + 90° + (18x -2)° = 360°</em>
<em>Perform addition and subtraction</em>
<em>90 + 12x + 2 +90 + 18x -2 = 360</em>
<em>30x + 180 = 360</em>
<em>Transpose 180 to the right side such as:</em>
<em>30x = 360 -180</em>
<em>30x = 180</em>
<em>Solve for x, we have:</em>
<em>x = 180 / 30</em>
<em>x = 6</em>
<em>Solving for the angle VXY, we have:</em>
<em>∠VXY = 12X + 2 = 12(6) + 2</em>
<em>∠VXY = 74°</em>
<em>The answer is 74°.</em>
Answer:
26. 106
27. -7.9% per year
28. shrinking
29. 31
30. $9560.92
31. $8243.61
Step-by-step explanation:
26. The value when t=0 is 106·.921^0 = 106·1 = 106
__
27. The rate of change is 0.921 -1 = -0.079 = -7.9% per year. It is a good idea to put the sign with the rate of change, so you know whether it is increasing or decreasing. Also, units are a good idea: "per year."
__
28. The negative rate of change means the population is shrinking.
__
29. In 15 years ...
y = 106·0.921^15 ≈ 30.8 ≈ 31
In 15 years the deer population is predicted to be 31 deer.
__
30. $5000(1 +.065/12)^(12·10) ≈ $9560.92 . . . . units are a good idea (dollars)
__
31. $5000·e^(.05·10) ≈ $8243.61 . . . . the exponential term has a time multiplier

Numbers are correct. IMO, some details need attention.
