Question

Answer the question below

Answer 1

Answer:

here is your answer

Step-by-step explanation:

given

twice of X is 30°less than y

solution

half of 30°=15°

so, x=15° (twice of 15° will be 30°)

Straight line =180°

y =180° - 30°

=150°

Answer 2

twice of x is 30⁰ less than y

2x = y - 30⁰ ( 1 )

x + y = 180⁰ ( angles in linear pair )

y = 180⁰ - x ( 2 )

placing equation ( 2 ) in equation ( 1 )

2x = y - 30⁰

2x = 180⁰ - x - 30⁰

2x = 150⁰ - x

2x + x = 150⁰

3x = 150⁰

x = 150⁰

3

x = 50⁰

placing x = 50⁰ in equation ( 2 )

y = 180⁰ - x

y = 180⁰ - 50⁰

y = 130⁰

therefore , x = 50⁰ and y = 130⁰
