Answer:
24 divided by 3 and 8 divided by 24
Step-by-step explanation:
The correct answer would be b) (12 + 3x)x
The value of x would be 60 degrees
explanation
===============================
the triangle has one missing angle that would be congruent to x since they are corresponding angles which means they are congruent.
We know that the triangle has to add up to 180 degrees. We add the 2 angles and get 120 degrees. We subtract 120 degrees from 180 to find the 3rd missing angle that is congruent to x degrees. 180-120=60 degrees. If 60 degrees is corresponding to x degrees, therefore, x should be equal to 60 degrees.
Hope this helps :)
