Question

Please help. Refer to the figure. Find the missing measure of each angle.

a) m<1= ?
b) m<2= ?
c) m<3= ?
d) m<4= ?
e) m<5= ?
f) m<6= ?

Answer 1

m<1= 80 due to the Corresponding Angles Postulate.

m<2= 360-(80+80)-(43+43) = 360-246 = 114/2 = 57

m<3= 57

m<4= 57+80+x = 180 ---> 137+x = 180 ---> x = 43

m<5= 180-43 = 137

m<6= 180-57 = 123
