The distance from Jacksonville to Tampa is 171 miles. The distance from Tampa to Miami is 206 miles. Use the Triangle Inequality Theorem to find the range for the distance from Jacksonville to Miami.
-35 mi < d < 377 mi
- -35 mi < d < 377 mi
-0 mi < d < 35 mi
-0 mi < d < 377 mi

In Jessica's room, the distance form the door D to the closet C is 4 feet. The distance from the closet to the window W is 6 feet. The distance from the window to the door is 8 feet. On a floor plan of her room, triangle CDW is drawn. Order the angles from least to greatest measure.
-I think it is : D, C, W. <--But could this be confirmed?
