Question

(73 points) Find the value of x.

Answer 1

Answer:

Option C. $98^{\circ}$

Step-by-step 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 :)
