Question

find the value of x​

Answer 1

Angle marked ax 3y and angle marked as 2y + 25 are equal

( alternate angles )

=> 3y = 2y + 25

=> 3y - 2y = 25

=> y = 25

Therefore, angle marked as 3y is = 3 * 25 = 75

Angle marked as x + 20 and angle 75 degree are equal

.( Correseponding Angles )

Therefore,

=> x + 20 = 75

=> x = 75 - 20

=> x = 55

Ans = x  = 55°

Answer 2

Answer:

25°

Step-by-step explanation:

3y=2y+25. ( alternate interior angles)

y=25

x+20 = 2y+25. (vertically opposite angles)

putting y=25

x=25°
