Select the correct answer from each drop-down menu. Use the diagram to complete the statement about the triangle inequality theorem.

a diagram showing segment AB and two segments of lengths 4.25 units and 4.75 units

If AB = 9, the diagram
the case of a degenerate triangle because
. The case of a degenerate triangle justifies the use of
inequality symbols in the triangle inequality theorem.

Two angles are adjacent, as shown in the diagram below. part a: use complete sentences to describe the relationship between the adjacent angles. part b. set up an equation and solve for x. in your answer, include the equation, your calculations and the value of x. part c. use your equation from part a and the value of x from part b to prove your equation to be true for the adjacent angles in the diagram.
