The value of y is 135°
The value of x is 45°
Step-by-step explanation:
3x + x = 180°. ( Co-interior angles)
4x = 180°
=> x= 45 °
Now,
3x = y. ( Vertically opposite angles )
3×45°=y
y=135°
Answer:
3x+x sum of interior angle sum is 180°
3x+x=4x
4x=180°
x=180°/4
x=45°
value of X is 45°
value of 3x will be 3 ×45=135°
3x = y
by, vertically opposite angle
angle Y =135°
