Question

in a triangle ABC if angle A= 45 and angle B = 70 .determine the largest side of the triangle

Answer 1

In triangle ABC,
                           ∠a +∠b+∠c=180°  (angle sum property of triangle)
                          ∠c=180°-135°
                          ∠c=45°
Now in triangle ABC ∠B is largest 
                              ∴side AC is greater.
