6) ∠FOC is vertical to ∠EOD
7) m∠POF is complementary to M∠FOB.
8) m∠AOC = 30°
How to determine congruent angles?
6) Vertical angles are angles that are opposite of each other when two lines cross. Thus;
∠FOC is vertical to ∠EOD
7) Given that m∠POF + M∠FOB = 90
Two angles are called complementary when their measures add to 90 degrees. Thus;
m∠POF is complementary to M∠FOB.
8) m∠BOC = 150. Thus;
m∠AOC = 180 - 150
m∠AOC = 30° because they are supplementary angles.
9) m∠EOA = 37. Thus;
m∠FOA = 180 - 37
m∠FOA = 143° because they are supplementary angles.
10) ∠EGH is adjacent to ∠OGH
This is from definition of adjacent angles
11) ∠EGH ≅ ∠DOB
m∠HGO = 128°, m∠DOB = 180° - 128° = 52° because they are supplementary angles.
12) m∠EOA = 67°, m∠DOB = 29°. Thus;
m∠EOD = 180 - (67 + 29)
m∠EOD = 84° because sum of angles on a line is 180°
13) m∠AOD + m∠DOB = 180 means that ∠AOD is supplementary to ∠DOB.
14) ∠COF ≅ ∠DOF and so we can say that;
FO is perpendicular to CD.
15) m∠COP = 72° and m∠POF = 31°. Thus;
m∠EOD = 72 + 31
m∠EOD = 103°
