Answer:

Hey! Your answer is B. 70°

Step-by-step explanation:

since you've got a line on two sides of the triangle, the top angle is equal to the angle in the bottom right corner. Since all triangles equal 180 when angles are added up, you'd add 55+55= 110 then subtract 180-110 to get 70. Therefore, X= 70°
