Step-by-step explanation:
Answer:
19. reflection (-1, -3)
20. translation (5, -3)
21. translation (0, -5)
22. reflection (1, 3)
23. translation (5, 6)
24. reflection (1, 3)
Step-by-step explanation:
35 + 52 + 3(x + 2) = 180
87 + 3x + 6 = 180 ( add the like terms and use distributive property)
93 + 3x = 180
-93 -93
3x = 87
÷3 ÷3
x = 29
( the sum of all triangle angles is 180)
