c and 118 degrees should add up to 180 degrees:
180 - 118 = 62 degrees for c
b and the unknown angle should also add up to 180 and from the line intersections are the same as c and 118.
b = 118
c = 62
Answer:
Explanation:
Find the missing angles
Angle b and 118 are vertical angles and vertical angles are equal
Angle c and 118 form a straight line which add to 180
c+118 = 180
c = 180-118
