Question

solve congruent triangle part's​

Answer 1

Step-by-step explanation:

40° + 90° + angle 1 = 180° (Angle sum property)

Angle 1 = 180° - 130°

Angle 1 = 50°

Angle 1 = Angle 3 (Vertically opposite angles)

Angle 3= 50°

Angle 7 + 90° = 180° (Linear pair)

Angle 7 = 90°

Angle 3 + Angle 5 + 90° = 180° (Angle sum property)

50° + 90° + Angle 5 = 180°

Angle 5 = 40°
