Question

please tell the answer

Answer 1

Step-by-step explanation:

x=2×30=60 , y=180-60=120

Answer 2

Answer:

x = 50 , y = 130

Step-by-step explanation:

given, 2x = y - 30 --------------------equation(1)

sum of angles of a straight line = 180 degrees ---------equation(2)

putting the value of y in equation(2) implies

  x + (2x + 30) = 180

   3x = 180 - 30

   3x = 150

   x = 150 / 3

 therefore x = 50

Now, putting value of x in equation (1) implies

2 x 50 = y - 30

 y - 30 = 100

 y = 100 + 30

 y = 130
