Can someone help please someone just took almost all my points bc they didn't answer it

Triangle inequality theorem state if each set of three numbers can be the lengths of the sides of a triangle. 1. 9, 8, 22. 2. 5,10,12. 3. 7,10,22. 4. 4,11,12. 5. 11,9,10. 6. 10,4,19. 7. 3,12,10. 8. 4,3,2. 9. 6,5,13. 10. 7,12,20. me .

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

The ratio of the measures of the three angles in a triangle is 2: 9: 4. find the measures of the angels
