Question

Please answer the 10th question

Answer 1

Answer:

a = 45°

b = 135°

c = 45°

Step-by-step explanation:

b=135° (vertically opposite angles are equal)

a=c (vertically opposite angles are equal)

By Angle sum property,

a+b+c+135 = 360°

2a + 135+135 = 360

2a = 360-270

2a = 90

a = 90/2 = 45°

c= 45° ( since a = c)

Answer 2

Answer:

a=45,b=135,c=45

Step-by-step explanation:

135 is vertically opposite angle of b so b=135

135 is linear angle of a, c so 180-135=45

so a=45,c=45
