How to find right answer

1 (A ) 26.5°  ( B ) 63.4°  

2 (A ) 22.6°  ( B ) 67.3°  

3 (A ) 24.7°     ( B ) 57°  

4 (A ) 33°     ( B ) 65.22°  

A elbow degree calculation 

Tan-¹( 600 ÷ 1200 ) = 26.5°  wrong answer 

Tan-¹( 500 ÷ 1200 ) = 22.6° wrong answer 

Tan-¹( 600 ÷ 1300 ) = 24.7° wrong answer 

√(500^² + 600^² = 781

Tan-¹(781 ÷ 1200 = 33° Right answer 

B elbow degree calculation 

Tan-¹( 1200 ÷ 600 ) = 63.4°  wrong answer

Tan-¹( 1200 ÷ 500 ) = 67.3°  wrong answer

90° – 33° = 57°   wrong answer

√(500^² + 1200^² = 1300

Tan-¹( 1300 ÷ 600 = 65.2° Right answer 

C travel pipe length calculation

√( 1300^2 + 600^2 = 1431.7 mm

√(1200^2 + 781^2 = 1431.7 mm
