Question

Please Help 100 points Answer all please

1) Can Kayla conclude that Triangle ABC and Triangle EDC are similar?
2) Based on your answer above, why can she or why can she not conclude the triangles are similar? (hint: use a similarity postulate)
3)Suppose DE is 30 feet. What can Kayla conclude about the width of the river? Show all work on the whiteboard below and explain your answer.

Answer 1

A. Yes

B. Because the three inside angles of both triangles would be identical.

C. Set up a ratio:

121/22 = AB/30

Solve for AB:

AB = (121 * 30) / 22

AB = 3630 / 22

AB = 165 ft.
