Question

Pllllllzzzzzz gelpo me aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa

Answer 1

Answer:

FE = 10, DE = 24

Step-by-step explanation:

We can use ratios to solve

13         5

----- = ----------

26      FE

Using cross products

13 FE = 26*5

Divide each side by 13

13 FE/13 = 26*5/13

FE = 10

13         12

----- = ----------

26      DE

Using cross products

13DE = 12*26

Divide each side by 13

13 DE/13 = 26*12/13

DE = 24

Answer 2

Answer:

D. DE = 24 yd, EF = 10 yd

Step-by-step explanation:

Solve for the unknown angles by setting up common ratios and cross multiplying. You can use this method because they are similar triangles.

For example, DE can be found by setting the ratios of AC/AB equal to the ratio of DF/DE.

13/12 = 26/x

Simply solve for x!
