Question

please help me plzzzzzzzz ​

Answer 1

2x + 3y = 180° { sum of angles on a straight line is 180°}

Given x = 30°

=> 2(30°) + 3y = 180°

=> 60° + 3y = 180°

=> 3y = 120° => y = 40°

Answer 2

Answer:

the answer is 40

Step-by-step explanation:

2x=2×30=60°

so,

3y+60=180

3y=180-60

3y=120

y=120/3

y=40
