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
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°
