Q.........

jawab soal mtk​

Jawab:

7x+5+2x+4=180

9x+9=180

9x=180-9

9x=171

x=171/9

x=19

∠RQS = 2x+4 = 2(19)+4 = 38+4 = 42 (opsi ke dua)

• Menentukan nilai x

<PQS + <RQS = 180°

7x + 5 + 2x + 4= 180

9x + 9= 180

9x = 180 - 9

9x = 171

x = 171/9

x = 19°

• Besar sudut RQS

<RQS = 2x + 4

= 2(19) + 4

= 38 + 4

= 42° (B)
