Isabella is making a huge flag of her country, the Republic of Seychelles, on a canvas 20 by 10 meters long,
To do that, she has to draw a diagonal line that begins at the bottom-left corner and ends at the top side of
the flag, 6.6 meters to the right
Since the ends of the diagonal line are too far to put a ruler between them, Isabella wanted to find the
angle of the diagonal and draw it using a protractor.
What is the angle, in degrees, between the diagonal line and the left edge of the flag?

How is working backward similar to solving an equation?

What is the range of the function? f(x)=-2|x+1|? a. all real numbers. b. all real numbers less than or equal to 0. c. all real numbers less than or equal to 1. d. all real numbers greater than or equal to 1
