Question

angle BAC and angle DAC are a pair of linear angles . whats the meausre of angle DAC if the measure of angle BAC is 25?

Answer 1

Answer: 155 degrees

Explanation:

Answer 2

Answer: The measure of the angle
`DAC` is 155.

Explanation:

1. By definition, when two lines intersect, a pair of linear angles is formed. These are two adjacent angles that are supplementary, which means that their measures add up 180 degrees.

2. Keeping this on mind, you have:

`m`∠
`BAC+`
`m`∠
`DAC=180`

3. Solve for the angle
`DAC`, as following:

`m`∠
`DAC=180-`
`m`∠
`BAC`

`m`∠
`DAC=180-25=155`
