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
