V ABCD - EFGH. What is the value of k? Your answer may be exact or rounded to the nearest tenth. Note: Images are not to scale. A E 4 mm k 8 mm B 6 mm H D 6 mm F 8 mm 4 mm C С

Respuesta :

Since rectangles ABCD and EFGH are similar, we can take the ratios of the corresponding sides of the rectangles

[tex]\frac{AB}{AD}=\frac{EH}{EF}[/tex]

[tex]\frac{8}{4}=\frac{k}{6}[/tex]

cross multiplying

8 x 6 = 4 x k

48 = 4k

4k = 48

Divide both sides by 4

k = 48/4

k = 12
