Answer:
left angle = 46° , angle on right = 44°
Explanation:
the angle on the left of the triangle and 134° are a linear pair and sum to 180° , that is
left angle + 134° = 180° ( subtract 134° from both sides )
left angle = 46°
the sum of the 3 angles in the triangle = 180° , that is
right + left + 90° = 180°
right + 46° + 90° = 180°
right + 136° = 180° ( subtract 136° from both sides )
right = 44°
