Question

Sum of 2 angles 140, find all angles​

Answer 1

3rd angle=110

4th angle=110

Answer 2

Answer:

the four angles are:

70° , 70° , 60° , 60°

Step-by-step explanation:

as it is forming an angle of 360° at angle P

as we know that vertically opposite angles arre equal so,

2x=140°

x=140/2

x=70°

thus the two angles are 70° each.

so,

360°=(70+70+x+x)° as opposite angles are equal.

360°=140°+2x

360°-140°=2x

120°=2x

120°\2 =x

60°= x

therefore,

the four angles are:

70° , 70° , 60° , 60°
