Question

Use the relationship between the angles in the figure to answer the question.

Which equation can be used to find the value of x?

x+49−28=180

​ x−49−28=180

​x + 49 + 28 = 180​

​x + 28 = 180​

Answer 1

x+49+28=180
This equation finds the degrees between the two angles we already know, and that angle equals the x

Answer 2

The answer is the option
`x+49\°+28\°=180\°`

Explanation:

see the attached figure with letters to better understand the problem

we know that

`m<ABC+m<CBD+m<DBE=180\°`

`m<CBD=x` -----> by vertical angles

`m<ABC=28\°` -----> given problem

`m<DBE=49\°` -----> given problem

substitute

`28\°+x+49\°=180\°`
