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
