Answer :-

i) As POQ is a line -

2x and 4x forms a linear pair.

Therefore,

⇒ 2x + 4x = 180°

⇒ 6x = 180°

⇒ x = 180/6

⇒ x = 30°

Value of x = 30°

ii) As AOP is a line,

( 3x ) and ( 2y + 15 ) forms linear pair.

a) x = 35°

⇒ 3x + 2y + 15 = 180°

⇒ 3 ( 35 ) + 2y + 15 = 180°

⇒ 105 + 2y + 15 = 180

⇒ 2y + 120 = 180

⇒ 2y = 180 - 120

⇒ y = 60 / 2

⇒ y = 30°

Value of y = 30°

b) y = 24°

⇒ 3x + 2y + 15 = 180°

⇒ 3x + 2 ( 24 ) + 15 = 180

⇒ 3x + 48 + 15 = 180

⇒ 3x + 63 = 180

⇒ 3x = 117

⇒ x = 117 / 3

⇒ x = 39

Value of x = 39°

Answer:

6)∠ROP+∠ROQ=180°(Linear pair)

2x+4x=180°

6x=180°

x=180°/6

x=30°

7)3x+2y+15°=180°(Linear pair)

a)If x=35°,

3x+2y+15°=180°

3(35°)+2y+15°=180°

105°+2y+15°=180°

120°+2y=180°

2y=180°-120°

2y=60°

y=60°/2

y=30°

b)If y=24°,

3x+2y+15°=180°

3x+2(24°)+15°=180°

3x+48°+15°=180°

3x+63°=180°

3x=180°-63°

3x=117°

x=117°/3

x= 39°
