Answer:
Angle EDH = 50°
Step-by-step explanation:
The picture above is the rectangle formed from the illustration above. The angle EDH is given as 5x° and angle HDG is given as 4x° . The angles EDG and FGD are right angles . That means both angles are equivalent to 90° .
Angle EDH = 5x°
Angle HDG = 4x°
Angle EDG = 90°
Therefore,
5x + 4x = 90
9x = 90
divide both sides by 9
x = 90/9
x = 10°
Angle EDH = 5x = 5 × 10 = 50°
