Answer:
Step-by-step explanation:
<u>∠A≅∠E, ∠B≅∠F and ∠C is common and congruent to itself, therefore</u>
- ΔABC ~ ΔEFC by AA similarity
<u>Ratio of corresponding sides is same. Get the equation below and solve for x:</u>
- EC/AC = CF/CB
- x/17 = (16+22)/16
- x/17 = 38/16
- x/17 = 19/8
- x = 17*19/8
- x = 40.375
75a^2b/25ab^2
= 75x axaxb /25xaxbxb
=3a/b
