Answer
Option A is correct.
Angle L = 55°
Explanation
To answer this, we need to note that the sum of angles in a triangle is 180°
So, we can solve for x by summing up the angles of this triangle and equating them to 180°
Angle J + Angle K + Angle L = 180°
2x + 45° + (x + 15)° = 180°
2x + 45° + x + 15° = 180°
2x + x + 45° + 15° = 180°
3x + 60° = 180°
3x = 180° - 60°
3x = 120°
Divide both sides by 3
(3x/3) = (120°/3)
x = 40°
Angle L = x + 15° = 40° + 15° = 55°
Hope this Helps!!!
