# 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

#### Solution:

$a = 11.2 cm \ \\ b = 6.5 cm \ \\ c = 26-a-b = 8.3 \ cm \ \\ a > c > b => α > γ > β \ \\ \ \\ α = 97.616^\circ \ \\ β = 35.116^\circ \ \\ γ = 47.268^\circ \ \\$
