Question

find the value of a and b​

Answer 1

Answer:

angle a = 100

angle b = 100

Step-by-step explanation:

angle b = angle50+angle30+ angle b

180 =80+ angle b

180-80 =angle b

100=angle b

angle a= angle y +angle x+ angle a

angle y=50 (alternative interior angle)

angle x=30(alternative interior angle)

so, 180=50+30+ angle a

180-80=angle a

100=angle a
