Answer:
24.23
Step-by-step explanation:
The tan(x) would equal to the opposite side over the adjacent one

Answer:
The answer is
<h2>
</h2>
Step-by-step explanation:
The distance between two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question
The points are D(2, 0) and E(8, 6
The distance between them is
