Answer:

  • 40. C. 40
  • 41. B. ∠ACE ≅ ∠ECB

Explanation:

#40

The triangle with angle x is isosceles as two sides marked as same.

The two angles opposite to equal sides measure x.

Sum of interior angles of the triangle is:

  • 100 + 2*x = 180
  • 2x = 180 - 100
  • 2x = 80
  • x = 40

#41

Common angle of the two triangles is angle C.

Correct choice is B
