Answer 1

》Garis dan Sudut

4.

Nilai x =

• 12x + 108° = 180°
• 12x = 180° - 108°
• 12x = 72°
• x = 72° ÷ 12
• x = 6°

Nilai z =

• 12x + 56° + 4z = 180°
• 12.6° + 56° + 4z = 180°
• 72° + 56° + 4z = 180°
• 4z = 180° - 72° - 56°
• 4z = 52°
• z = 52° ÷ 4
• z = 13°

Pada gambar tidak ada huruf y

Jadi hanya ada penyelesaian x dan z.

5.

Nilai x =

• 6x + 4° + 3x + 5° = 90°
• 9x = 90° - 4° - 5°
• 9x = 81°
• x = 81° ÷ 9
• x = 9°

Besar PQS =

• = 6x + 4°
• = 6.9° + 4°
• = 58°

Besar RQS =

• = 3x + 5°
• = 3.9° + 5°
• = 27° + 5°
• = 32°

Semoga Membantu

Answer 2

Penjelasan dengan langkah-langkah:

4.

nilai x

12x + 108 = 180°

12x = 180 - 108

12x = 72

x = 72/12

x = 6

__

nilai z

4z + 56 + 12x = 180°

4z + 12.6 = 180 - 56

4z + 72 = 124

4z = 124 - 72

4z = 52

z = 52/4

z = 13

5.

a. nilai x

6x + 4 + 3x + 5 = 90°

9x + 9 = 90

9x = 90-9

9x = 81

x = 81/9

x = 9

b. besar sudut PQS

= 6x + 4

= 6.9 + 4

= 54 + 4

= 58°

c. besar sudut RQS

= 3x + 5

= 3.9 + 5

= 27 + 5

= 32°
