Angle BAD and angle BAC are supplementary angles, which means they add up to 180 degrees.
180 = 122 + ?
Subtract 122 from both sides.
BAC = 58 degrees.
We know that the sum of all the interior angles of a triangle is 180 degrees.
180 = 24 + 58 + x
Combine like terms.
180 = 82 + x
Subtract 82 from both sides.
98 degrees = x
Answer choice A is correct
