<h3>Answers:</h3><h3>Area of parallelogram = 63</h3><h3>Area of triangle = 34</h3><h3>Area of trapezoid = 84</h3><h3>The trapezoid has the largest area</h3>
==================================================
Work Shown:
area of parallelogram = base*height
area of parallelogram = 9*7
area of parallelogram = 63
----------
area of triangle = (1/2)*base*height
area of triangle = (1/2)*10*6.8
area of triangle = 34
----------
area of trapezoid = height*(base1+base2)/2
area of trapezoid = 6*(13+15)/2
area of trapezoid = 6*(28)/2
area of trapezoid = 168/2
area of trapezoid = 84
The adjacent angles should add up to 180°

Step-by-step explanation:
Answer:
Percentage of error by Clare is estimated as 4.1667 %
Step-by-step explanation:
Height measured by Clare = 4 feet
Height measured by Doctor = 4 feet, 2 inches
Percentage error = ?
Percentage error = Difference/ Actual height *100
Percentage error = (2/ (4*12))*100
Percentage error = 4.1667 %
The accurate height is measured by Doctor, as he have more accurate measurement system.
Slope is -1 and y intercept is 8
