Answer:
Acute Triangle
Step-by-step explanation:
<u><em>Angles in a triangle add up to 180 degrees.</em></u>
So,
x+2x+2x = 180
=> 5x = 180
Dividing both sides by 5
=> x = 36
<u><em>So, The lengths are:</em></u>
=> 36
=> 72
=> 72
<em><u>Since all the angles are less than 90 degrees, It is an acute triangle.</u></em>

Answer:
y = x - 6.
Step-by-step explanation:
Do the division: 
x + 2 ) x^2 - 4x + 8 (  x - 6 <------- Quotient.
           x^2 + 2x
                     -6x + 8
                     -6x - 12
