Find the value of the marked angles in each of the following ( see image ). Please show workings.

The only given angle is 126°.

The angle to look for is marked by “))”​

the value of the missing angle is 117°

Step-by-step explanation:

the reflex angle on centre

=》 360° - 126°

( since, their sum is equal to 360° )

=》234°

so, the reflex angle measures 234°

now, the missing angle =

=》117°

( because the the angle made by the arc on centre is double the angle made at the circumference by the same arc )
