since it's a square, all sides are equal
therefore,
3x - 5 = x + 1
2x = 6
x = 3

sub x into AD, which is 3x-5
= 3(3) - 5
= 9 - 5
= 4

therefore AD is 4 units

Triangle ABC is similar to triangle DEF. The length of AC¯¯¯¯¯ is 12 cm. The length of BC¯¯¯¯¯ is 18 cm. The length of DF¯¯¯¯¯ is 10 cm.



What is the length of EF¯¯¯¯¯?



Enter your answer in the box.

Answers

Answer:If the triangles are similar, the ratio of corresponding sides will be equal.

AC / DF = BC / EF

Substitute their values,

12 / 10 = 18 / EF

EF = 18/12 * 10

EF = 3/2 * 10

EF = 30/2

EF = 15 cm

In short, Your Answer would be 15 cm
