Answer:

Step-by-step explanation:
y = x² + 3 x - 5 and x + y = -10 are the system of equations that do not have a real solution.
When the two equations are graphed and if they do not intersect, then there are no real solutions for the system of equations.
Answer:
Step-by-step explanation:
one angle is 80
let other angle be 'x'
then third angle will also be equal to x. (given)
using angle sum property,
x + x + 80 = 180. (1)
2x=100
x=50. (2)
therefore all angles are 80,50,50
