Question

In figure, AOB is straight line. Determine x.


​

Answer 1

Answer:

Step-by-step explanation:

sum of all angles = 180°

=> ∠AOD + ∠DOC + ∠COB= 180°

=> X° +(X-3)°+(2X-5)° =180°

=>4X°-8°=180°

=>4X°=188°

=>X°= 47°

Answer 2

Answer: x = 47°

Step-by-step explanation:

∠AOD + ∠DOC + ∠COB = 180° ----------> AOB is a straight line

x° + (x-3)° + (2x-5)° = 180°

x° + x° - 3° + 2x° - 5° = 180°

4x° - 8° = 180°

4x° = 180° + 8°

4x° = 188°

x° = 188°/4

x° = 47°
