Question

In the given figure, if m is parallel to n then find the value of x
60
55
50
45

Answer 1

Answer:

Answer =55

Step-by-step explanation:

3y=2y+25 Because Alternate interior angle

3y-2y=25

1y=25(y=25)

2×25+25

50+25

=75

x+20=2y+25

x+20=75

x=75-20

x=55

Answer 2

3y = 2y + 25 ( interior alternate angle)

3y - 2y = 25

y = 25

2y + 25° = x + 20° ( vertically opposite angle)

2 × 25 + 25 = x + 20°

50 + 25 - 20 = x

X = 55°
