Question

Someone can help me pleaseeee, for tonight with 2 or 3 will be fine FIND THE LENGTH

Answer 1

Answer:

4)..21 units

5). 15 units

6). 25 units

Step-by-step explanation:

4). Since ΔABC ~ ΔDEF,

   Their corresponding sides will be proportional.

   $\frac{AB}{DE}= \frac{BC}{EF}= \frac{AC}{DF}$

   Since, $\frac{AB}{DE}=\frac{AC}{DF}$

   $\frac{14}{42}=\frac{7}{x}$

   x = $\frac{42\times 7}{14}$

   x = 21 units

5). Since ΔABC ~ ΔDEF,

   $\frac{AB}{DE}=\frac{BC}{EF}=\frac{AC}{DF}$

   $\frac{AB}{DE}=\frac{BC}{EF}$

   $\frac{6}{9}=\frac{10}{x}$

   x = 15 units

6). Since ΔABC ~ ΔDEF,

   $\frac{AB}{DE}=\frac{BC}{EF}=\frac{AC}{DF}$

   $\frac{BC}{EF}=\frac{AC}{DF}$

   $\frac{6}{30}=\frac{5}{x}$

   x = 25 units
