1. Answer:

   In a right angle triangle total sum of angles = 180

   if 57 is first angle so the another angle should be 90 as it is a right angle triangle

   let the third angle be x

   therefore, 180 = 57 + 90 + x

   180 = 147 + x

   180 – 147 = x

   33 = x

   therefore the third angle is 33°

2. Answer:

   In a right angle ∆ one of the angle is 90°

   one of the angle given is 57°

   So the unknown angle= 180-(90+57)

   180-147=33°
