Question

Given that triangle ABC~ Triangle DEF solve for x

Answer 1

B

Explanation:

Given that the triangles are similar then the ratios of corresponding sides are equal, that is

`(AB)/(DE)` =
`(BC)/(EF)` , substitute values

`(35)/(5)` =
`(42)/(x)` ( cross- multiply )

35x = 210 ( divide both sides by 35 )

x = 6 → B

Answer 2

x=6

bcz 5×7=35

6×7=42

7×7=49
