Question

PLEASE HELP IF POSSIBLE ! :)

Answer 1

x = 9 then the other box, is something ?*2

Answer 2

Explanation:

As it is said that the triangles are similar so the ratio of the corresponding sides are equal so

AB / ED = BC / EF

x² / 18 = 7 / 14

x² / 18 = 1 / 2

2x² = 18

x² = 18 / 2

x² = 9

x² =( + 3)²

Therefore

x = 3 or x = - 3

Hope it will help :)❤
