B) 45 degrees


C) 62 degrees


D) 73 degrees

What is the value of measure d A 28 degrees B 45 degrees C 62 degrees D 73 degrees

Answer :

The answer is 62 degrees

sum of the angle in a straight line = 180° d=180°-118°

d= 62°

sum of the angle in a straight line = 180°

107°+ b° = 180°

b°=180° - 107 °

b°=73°

sum of the angle in a triangle = 180°

b°+d+45° = 180°

73+d+45° = 180°

118°+d= 180°

d=180°-118°

d= 62°
