Interior Exterior Angles Size

Calculate the sizes of the remaining inner and outer angles. Alpha with comma α '= 140 ° and beta with comma β' = 100 °.

Final Answer:

A =  40 °
B =  80 °
C =  60 °
C1 =  120 °

Step-by-step explanation:

A1=140  B1=100  A=180A1=180140=40
B=180B1=180100=80
C=180(A+B)=180(40+80)=60
C1=180C=18060=120
