Question

A central angle of a circle measures 42 degrees. What else can be shown to measure 42 degrees?

Answer 1

Vertically opposite angles

Explanation:

Given

`\theta = 42^\circ`

Required

What else can measure
`\theta = 42^\circ`

The question has missing options. So, I will give a general explanation.

Using the attached image as a point of reference.

Given that:

`\theta = 42^\circ`

The value of b is calculated as:

`b = \theta`

Because b and
`\theta` are vertically opposite angles

This gives:

`b = 42^\circ`

So, one possible answer to the question is a vertically opposite angle
