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°
