By applying the theorem of similar triangles and their side ratio, the length of EA is approximately: 16.7 cm
Triangle CDB and triangle CEA are similar triangles.
Based on the theorem of similar triangles, the ratio of the side lengths of triangle CDB to the corresponding side lengths of triangle CEA would be equal.
Given:
CD = 9 cmCE = 9 + 6 = 15 cmDB = 10 cmThus:EA/DB = CE/CD
SubstituteCross multiplyDivide both sides by 9EA = 16.6 cm
Therefore, by applying the theorem of similar triangles and their side ratio, the length of EA is approximately: 16.7 cm

DB : EA = DC : EC
10 : x = 9 : (9 + 6)
10 : x = 9 : 15
x = (10 * 15) : 9
x = 150 : 9
x = 16.66
16.66 cm is your answer
Ответ:
yes
