Question

In triangle ABC ,a=65°,b=30°.The side of this triangle which is longest is what?

Answer 1

Answer:BC=c=85° is the longest side

Step-by-step explanation:AB+CA+BA=180° ( since sum of angles of triangle must be 180°)

=a+b+c=180°

=65°+30°+c=180°

=95°+c=180°

=c=180°-95°

=c=85°

There fore angle c is the longest angle
