I think shes right probably i might be wrong
Sum of interior angles of a pentagon = 540 degrees
So 540/5 = 108 degrees
A single interior angle of a pentagon is 108 degrees
Answer:
Option- one is correct.
The given system of equations have one solution that is (7,-21)
Step-by-step explanation:
Given system of equations are
Now to the solution:
To solve the given system of equations using substitution method.
That is substitute equation(1) in equation (2) we get
(here y=-3x)
(adding the like terms)
Therefore x=7
Now substitute x=7 in equation (1) we get
Therefore the solution is (7,-21)
Therefore Option- one is correct.
The given system of equations have one solution that is (7,-21)
