Triangles ABC and DEF are similar. Find the lengths of AB and EF. Right triangles A B C and D E F. Side A B is 5 x, side B C is 4, and hypotenuse A C is unknown. Side D E is 5, E F is x, and hypotenuse D F is blank. a. AB = 2; EF = 10 c. AB = 20; EF = 4 b. AB = 10; EF = 2 d. AB = 4; EF = 20 Please select the best answer from the choices provided A B C D

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

what's the question?

step-by-step explanation:

there is no question.

the answer is a if my teacher taught me correct

divide the numbers
