Question

Find b,c,d.Give reasons​

Answer 1

Answer:

Linear pair.

Step-by-step explanation:

angle b + 42 = 180° (Linear pair)

angle b = 180 – 42

angle b = 138°

angle b = angle d (Top angle.)

angle d = 138°

angle d + angle c = 180° (Linear pair)

138° + angle c = 180°

angle c = 180 – 138

angle c = 42°
