Question

find the unknown value​

Answer 1

Answer:

a = 58 degree

c=58 degree

b= 122 degree

Step-by-step explanation:

180-122=58 ( angles in a linear pair)

a=c

58=c (opposite angles)

122 =b (opposite angles

Answer 2

Answer:

angle b =122°( vertically opposite angles)

angle b+ angle c= 180°

122°+c=180°

c=180-122

c=58°

angle a=angle c (vertically opposite angles)
