tolong jawab pake cara yah​

Answer 1

Jawaban:

yang a

180 = 108 + 12×

180-108 = 12 ×

72 = 12 ×

72/12 = ×

6° = ×

Penjelasan dengan langkah-langkah:

yang b

180 = 56 + 5× + 2y

180 = 56 + 5(6) + 2y

180 = 56 + 30 + 2y

180 = 86 + 2y

180-86 = 2y

94 = 2y

94/2 = y

47° = y

yang c

180 = 4z + 12× + 56

180 = 4z + 12(6) + 56

180 = 4z + 72 + 56

180 = 4z + 128

180 - 128 = 4z

52 = 4z

52/4 = z

13° = z
