Answer:

can't really see the photo, but from what i can tell, the answer would be D. 45 degrees.

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180

2x + x + 45 = 180

3x + 45 = 180 ( subtract 45 from both sides )

3x = 135 ( divide both sides by 3 )

x = 45° → D
