No it is not a right triangle. Because using Pythagorean's Theorem 6 squared, 36, plus 21 squared, 441, is 477. And when you do 32 squared is equals to 529. And therefore 477 is not equal to 529.
This triangle is a scalene triangle because all three of the side lengths aren't equal.All of the three angles have different measures.This triangle would have been classified as acute because the angles are less than 90 degrees.If all angles were 90 degrees then it would be right and if they were more than 90 it would have been an obtuse triangle.Hope this helped!!!!!!!!

Answer:
The solution is any point in the common part of red and blue
The two lines intersect each other at (4 , 7)
Step-by-step explanation:
∵ y > 1/4 x + 6 ⇒ y = 1/4 x + 6
∵ y > 2x - 1 ⇒ y = 2x - 1
∴ 2x - 1 = 1/4 x + 6
∴ 2x - 1/4 x = 6 + 1
∴ 7/4 x = 7 ⇒ x = 7 ÷ 7/4
∴ x = 4
∴ y = 2(4) - 1 = 7
∴ The two lines intersect each other at (4 , 7)
∴ The solution is any point in the common part of red and blue
