Me asap i will mark branlist just explain

Measure of Angle 5 = 150 degree.

Step-by-step explanation:

Given line g and h are parallel lines.

Let angle measuring be a.

From figure we can see that both are Linear Pair Postulate,

i.e.

So,

  ------------(equation 1)

Now, are alternate interior angles, and alternate interior angles are equal.

i.e.

Therefore    ------------(equation 2)

Now, both are Linear Pair Postulate,

i.e.

   ------------------(from equation 2)

---------(equation 3)

Now,   are vertically opposite angles, and vertically opposite angles are equal.

So,

-----------------(from equation 3)
