Answer 1

Answer:

x = 21°

Step-by-step explanation:

105°+54°=159°

180°-159°=21°

Angle BCA=Angle x

So angle x is 21°

Answer 2

Answer:

x = 21

Step-by-step explanation:

Angle B (54 degrees) and Angle DAB are alternate interior angles, meaning that they are congruent. So since Angle B is 54 degrees, Angle DAB is also 54 degrees.

So to find x, add 105 and 54 together:

105 + 54 = 159

Then, subtract 159 from 180 (because a straight line will always be 180):

180 - 159 = 21

So, x = 21 degrees.
