Answer:
Step-by-step explanation:
B
Vertical angles are always the same size. if they are supplementary the measures must add to 180. 180/2=90. vertical angles are supplementary only when they are right angles, our 90°
Answer:
B = 155° , C = 25° , D = 155°
Step-by-step explanation:
Given
A = 25°
C = A = 25° [ Vertically Opposite angles ]
Now
A + B = 180°( being linear pair)
25° + B = 180°
B = 180° - 25°
B = 155°
Also
D = B = 155°( vertically opposite angles )
Answer:
range=8, mode=1 Median=3 mean=4
Step-by-step explanation:
range= subtract largest from smallest
mode= most frequent
median= middle in an ordered data set
Mean= add them all up and divide by how many you addded up
