Question

(73 points) Find the value of x.

Answer 1

Option C.
`98^(\circ)`

Explanation:

`\angle DAB + \angle BAC = 180` (the two angles sum to the angle of a straight line:
`180^(\circ)`)

`122+\angle BAC = 180`

`\angle BAC = 180-122`

`=58^(\circ)`

`24+58+x = 180` (sum of interior angles of triangle is
`180^(\circ)`)

`82+x=180`

`x=98^(\circ)`

∴ Option C is correct.

Hope this helps :)
