Question

Find x and y, if AB is a straight line.
​

Answer 1

Answer:

x+2x =3x

so 3x+3x+60 =180

6x=180-60

6x=120

x=20

Answer 2

Answer:

Line AB is a straight line so angles forming there will sum up as 180 degrees.

X+3X= 180 degree

4X=180 degrees

X=180/4= 45 degree.

Now, AB line below

60+ Y + 2X=180 degree

60 +Y+ 2(45) = 180 degree

60+Y+90=180 degree

Y = (180- 150) degree

Y= 30 degrees
