Answer:
(a) x = 36
(b) x = 12
Step-by-step explanation:
2. (a) 2x + 3x = 180° (linear pair)
5x = 180 => x = 180/5 = 36
(b) 5x + 7x + 3x = 180° (linear pair)
15x = 180 => x = 180/15 = 12
a) Here,
2x+3x=180° [°.°Linear Pairs]
[tex]2x + 3x = 180° \\ \implies 5x = 180 \\ \implies x = \frac{180°}{5} \\ \implies x = 36°[/tex]
.°. x = 36°

b) Here,
5x+7x+3x= 180° [°.° Linear pairs]
[tex]5x + 7x + 3x = 180° \\ \implies 15x = 180° \\ \implies x = 12°[/tex]
.°. x=12°
