Classify the triangle as acute, right, or obtuse and classify it as equilateral, isosceles, or scalene.
2 answers:
The triangle is Obtuse and scalene , Option C is the correct answer.
<h3>What is a Triangle ?</h3>A triangle is a polygon with three sides , three angles and three vertices.
A triangle can be classified as Acute , Right or Obtuse on the basis of the angle in a Triangle .
and it is classified as scalene , equilateral and isosceles on the basis of the length of the sides of a triangle.
The triangle given in the question has all the sides different , so it is a scalene triangle.
One of the angle is obtuse angle and so it can be classified as a Obtuse Angle Triangle.
Therefore , Option C is the correct answer.

Answer:
{x,y} = {6/5,23/10}
Step-by-step explanation:
[1] 7x + 2y = 13
[2] 4x + 4y = 14 <---------- linear equations given
Graphic Representation of the Equations : PICTURE
2y + 7x = 13 4y + 4x = 14
Solve by Substitution :
// Solve equation [2] for the variable y
[2] 4y = -4x + 14
[2] y = -x + 7/2
// Plug this in for variable y in equation [1]
[1] 7x + 2•(-x +7/2) = 13
[1] 5x = 6
// Solve equation [1] for the variable x
[1] 5x = 6
[1] x = 6/5
// By now we know this much :
x = 6/5
y = -x+7/2
// Use the x value to solve for y
y = -(6/5)+7/2 = 23/10
// Plug this in for variable y in equation [1]
[1] 7x + 2•(-x +7/2) = 13
[1] 5x = 6
// Solve equation [1] for the variable x
[1] 5x = 6
[1] x = 6/5
// By now we know this much :
x = 6/5
y = -x+7/2
// Use the x value to solve for y
y = -(6/5)+7/2 = 23/10
