Since they are supplementary angles (180°)

45° + (2x-5)° = 180°

(2x-5)° = 180° - 45°

(2x-5)° = 135°

2x° = 135° - 5°

2x° = 130°

x° = 130/2°

x° = 65°

Answer:

x=70

Step-by-step explanation:

Since they are supplementary angles (180°)

45° + (2x-5)° = 180°

(2x-5)° = 180° - 45°

(2x-5)° = 135°

2x° = 135° + 5°

2x° = 140°

x° = 140/2°

x° = 70°
