Question

please give me answer​

Answer 1

Answer:

Q1) 70°

Q2) a=60°

b=60°

Q3) <AOD=65°

<AOC=115°

<DOB=115°

Answer 2

Answer:

1. 110+x=180. ( linear pair)

x=180-110

x=70°

2. 30+90+a= 180. (straight line)

120+a=180

a=180-120

a=60°

a=b. (vertically opposite)

3. angle AOD=65°. (vertically opposite angles)

angle AOC+angle AOD=180°. (linear pair)

angle AOC+65=180

angle AOC=180-65

angle AOC=115

angle AOC=angle DOB. ( vertically opposite angles)

115=angle DOB
