Answer:
h=60
Step-by-step explanation:
The angle that is 120 degrees and the angle that is h degrees are called same side interior angles
Same side interior angles are supplementary, meaning that they add to 180 degrees
To find h we can use Measures addition postulate to find the unknown value h
h+120=180
h=60
<span>In this case, that would be 13,000.</span>
180-2(55)-x=0
180-110-x=0
70-x=0
-x=-70
x=70°
