Answer:
No
Step-by-step explanation:
Use the pythagorian theorm to find whether it's a right triangle or not.
So the hyp will be the largest number. And the hyp must be equal to the sum of b and c squared
5.2 squared= 2.4 squared+ 4m5 squared
27.04= 26.01
It's not equal so the triangle isn't a right triangle.
When the lines are parallel then there is no solution to the system of equations.
This happens because the intersection is the solution. And when there is no intersection then there is no solution.
