Unit: Differentiation
Answer:
134 degrees
Step-by-step explanation:
what you do, is see that they are alternate interior angles so all you do is subtract 46 from 180 so that makes 134.
Let the width be x.
Then,Length = ( 2x - 3 ) m
<u>According to the question, </u>
Area of rectangle = 665 m² [ Given ]
Formula: Area of rectangle = Length × Width




<u>By split middle term </u>




Note: Ignore negative number.
Now,
Width of a rectangle = 19 m
Length of a rectangle = 2x - 3 = 2 × 19 - 3 = 38 - 3 = 35 m
