Answer:
- 40. C. 40
- 41. B. ∠ACE ≅ ∠ECB
Step-by-step 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
