If we focus on the blue triangle below, we see that we already know that two of the angles are 90° and 50°
Since all three angles in a triangle must add to 180°, we can conclude that the missing angle is 40°
This means we can write: x° + 15° = 40°
Solve the equation to get: x = 25
Answer: B
Cheers,
Brent

since,
X+15+50+90 = 180
X=180-155 = 25
IMO B
X+15+50+90 = 180
X=180-155 = 25
IMO B
