yg bisa tolongin 20 menit lagi di kumpulin​

Jawab:

130 derajat

Penjelasan dengan langkah-langkah:

180 = x + 17 + x + 3

180 = 2x + 20

2x = 160

x = 80

x + 3 + 2y - 3 = 180

80 + 3 + 2y - 3 = 180

80 + 2y = 180

2y = 100

y = 50

Maka x + y = 80 + 50 = 130 derajat

Jawaban:

jadi besar x + y = 127 °

Penjelasan dengan langkah-langkah:

X+17 + X + 3 = 180 °

2x + 20= 180

2X = 180-20

2x = 160

X = 160 : 2

X = 80

X + 17 = 2y - 3

X + 17 = 80 + 17 = 97

2y - 3 = 97

2y = 97-3

2y = 94

y = 94 : 2

y = 47

X + Y = 80 + 47

= 127

jadi besar x + y = 127 °
