Question

hi how to solve this please answer it's urgent​

Answer 1

Step-by-step explanation:

angle 4 and angle 5 are consecutive interior angles

So angle 4 + angle 5 = 180°

2x+9 + 6x -21 = 180

8x = 192

x = 24

Now angle 4 = 2× 24 + 9 = 57°

angle 5 = 6× 24 -21 = 123°

Now angle 2 = angle 4 and angle 5 = angle 7 as they are vertically opposite angles

So angle 2 = 57°

and angle 7 = 123°

Answer 2

Answer:

Measurement of < 2 = 57°

and < 7 = 123°
