Answer:

A. 98

Step-by-step explanation:

This is the exterior angle theorem I'm pretty sure.

This means that 24 + x, would equal 122.

So, 24 + x = 122.

Do the algebra. Subtract on both sides, so 122 - 24 would be 98.

So x = 98

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
