Answer:
<h2>The side DE is 4.2 units long, approximately.</h2>Step-by-step explanation:
In the given triangle, side DE is the hypothenuse. So, we can use Pythagorean's Theorem, where both legs are 3 units long.
Therefore, the side DE is 4.2 units long, approximately.
y = 4
first note that the right side simplifies to 12, equation can be written
= 12 ( multiply both sides by 0.8 )
2y + 1.6 = 9.6 ( subtract 1.6 from both sides )
2y = 8 ( divide both sides by 2 )
y = 4
