The vertices of kite DEFG are (5,5), (8, 2), (5,-4), and (2, 2), respectively. Prove that the diagonals of kite DEFG are
perpendicular lines. Complete your work in the space provided or upload a file that can display math symbols if your
work requires it.

Step-by-step explanation:

The answer to the question above is provided in the attached graph sheet.

Perpendicular lines are formed when two straight lines meet to make angle 90°. From the diagram in the graph sheet, the diagonal lines (two straight lines) of the kite cut across each other such that the lines form 4 right-angled triangles which have angles of 90°.

Hence, the diagonals of kite DEFG are perpendicular lines.

step-by-step explanation:

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
