Answer:

∠1 = 103°

Step-by-step explanation:

supplementary angle to 136° = 180° - 136° = 44°

∠1 = 180° - 33° - 44° = 103°

Step-by-step explanation:

Let the unnamed angle in the triangle be x.

x + 136 = 180 (Sum of angles on the same straight line)

x = 180 - 136

= 44

Angle 1 + x + 33 = 180 (Sum of angles in a triangle)

Angle 1 + 44 + 33 = 180

Angle 1 + 77 = 180

Angle 1 = 180 - 77

= 103
