Answer:

d = 37°

Explanation:

d° and the unmarked angle and alternate angles

68° 75° and the unmarked angle form a triangle

The sum od the interior angles of a triangle add upto 180°

So, 180° = 75° + 68° + unmarked angle

Lets call the unmarked angle 'x'

180° = 75° +68° + x

x = 180° - 75° + 68°

x = 180° - 143°

x = 37°

The unmarked angle is 37°

Remember d° and the unmarked angle are alternate angles

So, d° = 37°
