The middle point aka the E has to be in the middle and then the first and last points don’t matter
40°
Step-by-step explanation:
∠ACB = ∠DCE ( vertically opposite angle )
Now...
a + 90° + 50° = 180° ( the sum of interior angle of triangle is 180° )
a + 140° = 180°
a = 180° - 140°
a = 40°
hence the value of a is 40°
