Question

AOB is a straight line. Find angle AOC, angle BOD​

Answer 1

Answer:

Given: AOB is a straight line...

          ∠COD = 65°

          ∠DOB = (2x-20)°

To find: 1) ∠AOC

             2) ∠DOB

Solution: Let ∠AOC =x°

As AOB is a straight line ...

∴ ∠AOC+∠COD+∠DOB=180°

x+65+2x-20=180  ( from given)

3x+45=180

3x=135

x=45

∠AOC=x=45°

∠DOB=2x-20

=2(45)-20

=90-20

∠DOB=70°
