Find the measure of angle a and angle b. Explain.

b=78 a=102

Step-by-step explanation:

b=78 becasu of z rule and a=103 becuaes 180-78 = 102

a= 102

b = 78° (Corresponding angles are equal)

Step-by-step explanation:

a and b forms a semi circle

angles on a straight line adds up to 180

so if b is equal to 78°

then u will subtract 78 from 180

180-78= 102°

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

i agree because i see the other persons thinking is clear
