Question

Plz help me. Asap I need help

Answer 1

Answer:

(8x - 1) + (3x +4) + (3x + 9) = 180 (sum of angles in a Triangle is 180)'

8x+3x+3x -1 +4 +9 = 180

14x + 12 =  180

14x = 180 - 12

x = 168/ 14 = 12

first angle = 8 * 12 -1 = 95

Second angle = 3*12 + 9 = 45

Third angle = 3*12 +4 = 40

(8x - 1) + (3x +4) + (3x + 9) = 180____ (sum of angles in a Triangle is 180)'

8x+3x+3x -1 +4 +9 = 180

14x + 12 = 180

14x = 180 - 12

x = 168/ 14 = 12

• first angle = 8 * 12 -1 = 95

• Second angle = 3*12 + 9 = 45

• Third angle = 3*12 +4 = 40
