Bantu jawab kak soal ya kak
16. a
18. 16°15'-12°49'= 03°26' D
20. (15x-6)°(8x+4)° = 90°
15x+8x = 90°+6°- 4°
23x = 92°
x = 4°
<ABD = 15x – 6°
= 15×4 – 6°
= 60°-6°
= 54° C
21. (4x+5)°(5x-12)°(8x)° = 180°
4x+5x+8x = 180°-5°+12°
17x = 187°
x = 11°
<ABE = 4x + 5°
= 4×11 +5°
= 44° + 5°
= 49° C
22. a
23. (gambar kurang jelas)
Maaf jika salah
Semoga membantu
16. AD dengan CG
17. 150°
18. 16°15' – 12°49' = 3°26
19. 2+3 = 5
°
20. (15x+8x-6+5)° = 90°
(23x-2)° = 90°
23x° = 90°
x = 4°
∠ABD = 15x-6
= 15(4)-6 = 60-4 = 54°
21. (4x+8x+5x+5-12)° = 180°
(17x-7)° = 180°
17x = 187°
x = 11°
∠ABE = 4x+5
= 4(11)+5
= 49°
22. – ∠K1 dan ∠L3
- ∠K2 dan ∠L4
