Question

A video game console requires a 140 degree span in a room. The angles on each side are congruent. Write and solve an equation to determine the measure of each angle.

Answer 1

The measure of each angle is
`20\°`

Explanation:

see the attached figure to better understand the problem

Let

x------> the angle on each side

we know that

`x\°+140\°+x\°=180\°`

solve for x

`2x\°=180\°-140\°`

`2x\°=40\°`

`x=20\°`
