Answer:
15
Step-by-step explanation:
Diagram would be helpful.... I am assuming this is a right triangle with legs ratio 3:4
19. 60* - a straight line is 180* - the other side which is 120* (supplementary)
20. 132* - the angle below is the same as the other side of this angle, 180* - 48* (same side interior angles)
21. 48* - these are the same angle just in different placements (corresponding angles)
22. 70* - same angles just different placement (alternate interior angles)
23. 85* - these are vertical angles so they’re the same
24. 114* - same angle just different placement (alternate exterior angles)
27% + 18% = 45%
Hope you understand problems like this better in the future
