Answer:
To find the answer, we need the measurement of the sides. However just by looking at the triangle I would say it is a Isosceles triangle.
Step-by-step explanation:
An Isosceles triangle has has 2 side that are the same length. Looking at the picture the bottom appears to be longer than the sides of the triangle.
2/5x + 1.5y = 7x - 2y
1.5 y + 2y = 7 x - 2/5x
You can this
1.5 y + 2y = 7x - 0.4x
3.5y = 6.6x
