Matematika carilah nilai a, b, c dan d pada tiap tiap segitiga berikut​

carilah nilai a, b, c dan d pada tiap tiap segitiga berikut​

Penjelasan dengan langkah-langkah:

(i) 2a + 3a + 35° = 180°

(2+3)a = 180° – 35°

5a = 145°

a = 145°/5

a = 29°

(ii) 3 × 2b = 180°

2b = 180°/3

2b = 60°

b = 60°/2

b = 30°

(iii) 2 × c + 3c = 180°

2c + 3c = 180°

5c = 180°

c = 180°/5

c = 36°
