Answer:
Because a straight line is 180°, the other angles to these 2 would each be 180°-150°=30°. The same angles would be between line b and line c because line b and line a are parallel and line c is the same. Therefore, the measures of all the angles would be 30° or 150°.

denotes the additional cookies that need to be made by Walter besides 15 cookies made by him so far
Step-by-step explanation:
Number of cookies made by Walter so far = 15
He is asked by his coach to make at least 20 cookies but no more than 55.
Let
denotes the additional cookies that need to be made by Walter besides 15 cookies made by him so far.
The inequality is 
Now solve this inequality.

Answer:
132°
Step-by-step explanation:
Angle JKH and IHK are alternate interior angles, and thus congruent.
Since JKH is 132 degrees, so is IHK
