The aspect ratio

The aspect ratio of the rectangular triangle is 13: 12: 5. Calculate the internal angles of the triangle.

Correct answer:

A =  90 °
B =  67.3801 °
C =  22.6199 °

Step-by-step explanation:

a:b:c=13:12:5 a=13x b=12x c=5x  a2=b2+c2 (13x)2=(12x)2+(5x)2 132=122+52 169=144+25 169  A=90=90
sinB=ab=13x12x  B=π180°arcsin(12/13)=67.3801=67°2249"
C=90B=9067.3801=22.6199=22°3711"
