Angles and sides of the triangle

Triangle ABC has a circumference of 26 cm. Lengths of the sides are as follows: a = 11.2 cm; b = 6.5 cm. Arrange the interior angles in order of its size.


« Correct result





Wrong answer

Solution:

a = 11.2 cm $    $ b = 6.5 cm $    $ c = 26-a-b = 8.3   cm $    $ a > c > b  =>  alpha  >  gamma  >  beta $    $  $    $  alpha  = 97.616** circ $    $  beta  = 35.116** circ $    $  gamma  = 47.268** circ $    $
