a = 70° [because vertically opposite angles are equal.]

c + 150° = 180° [They are linear pair]

=> c = 180° - 150°

=> c = 30°

a+b+c= 180° [Sum of all angles of a triangle=180°]

=> 70° + b + 30° = 180°

=> 100° + b = 180°

=> b = 180° - 100°

=> b = 80°

two angles form a straight angle. what is the one angle measures 89°. what is the measure of the other angle?
ICE Princess25 [194]
A straight line is = to 180 degrees (straight angle) so the formula would be
X+89=180
subtract the 89 from both sides and you get x=91
so the other angle is 91 degrees
