Answer:

AB = 2

Step-by-step explanation:

the triangles are similar so that means there is a constant ratio for each side length. so comparing the ratios from the bigger triangle to the smaller triangle, leaves us with 9/3 and 15/5. if you take those and divide them you get 3 for both of them which is the constant. so then in order to find the length of AB just take the side length of XY (6) and divide it by 3 (the constant ratio) and there you have your answer!

hope this helps.

Answer:

Step-by-step explanation:

Remark

An angle bisector sets up a triangle ratio that looks like the following proportion.

3x - 3 5x

====== = ====== Cross multiply

24 44

44*(3x-3) = 24*5x Remove the brackets on the left

132x - 132 = 24*5x Combine the right side

132x - 132 = 120x Add 132 to both sides

132x = 120x + 132 Subtract 120x from both sides

132x- 120x = 132 Combine

12x = 132 Divide by 12

x = 11
