If the base of a triangle is doubled then new area= times old area

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 .

Add the fractions, and simply the result to lowest terms. 2/3 + 2/7= ?

The trigonometric ratios sine and secant are reciprocals of each other
