Answer:
Step-by-step explanation:
The vertical angles at E are the same and are included in both triangles ABE and CDE. Since the sum of angles of a triangle is 180°, the sum of the angles at A and B will match the sum of the angles at C and D. That is, when either sum is added to the angle at E, the result will be 180°.
A = (C+D)-B = (43 +35 -18)°
A = 60°
