Question

The triangle ABC is given. The ratio of the interior Angel is alpha: beta: gamma = 3:2:13 and the difference of two sides is a-b= 3 . The length of the longest side of the triangle is?​

Answer 1

Answer:

Step-by-step explanation:

Let common factor of ratio of angles is X.

Ratios are 2:3:5 given.

So, 2*X+3*X+5*x=180° — sum of three angles of a triangle.

Now,

10*X=180°

So, X=18°.

Hence angles are 36° , 54° and 90°.
