Y- intercept is none
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given equation of the line 
The equation of the straight line in slope - intercept form
y = m x + c

slope of the line 
Y- intercept is none
1/9 - (-2/5 - 8/9) = 1/9 + 2/5 + 8/9 = 1 + 2/5 = 7/5 or 1 2/5
Answer: 
Step-by-step explanation:
Observe in the figure given in the exercise that four right triangles are formed.
In this case you can use the following Trigonometric Identity to solve this exercise:
From the figure you can identify that:

Then, you can substitute values:

The next step is to solve for DE in order to find its value. This is:

Finally, rounding the result to the nearest tenth, you get that this is:

Answer:
