Math home work I have two questions

Answer:
2d = 58 (If you are just finding d then d = 29)
Step-by-step explanation:
69 + 53 = 122
180 - 122 = 58
Answer:
29
Step-by-step explanation:
The total degree of a triangle is 180 so
(69 + 53) + 2d= 180
122 + 2d= 180
2d= 180-122
2d= 58
Divide both side by 2
which 29
BUT
i dont really understand if the 2 was the multiple or it just "2d"
in that case "2d" would be 58.
