0.2 = 1/5 = 20%

0.04 = 1/25 = 4%

0.65 = 13/20 = 65%

1 = 1/1 = 100%

0.25 = 1/4 = 25%

1.5 = 3/2 = 150%

0.8 = 4/5 = 80%

0.26 = 13/50 = 26%

0.01 = 1/100 = 1%

Answer:

The value of the line segment $ED$ is 36.

Step-by-step explanation:

The hypotenuse represents the longest side in the right triangle. In this case, FD represents the hypotenuse as it is a multiple of 13. Based on the trigonometric relations described in the statements, we get the following relationships by definition of cosines:

$\cos D = \frac{ED}{FD}$ (1)
