Answer 1

Answer:

Step-by-step explanation:

50 + 60= 180

= 180-110

=70

so a= 70

Answer 2

Answer:

BC is the greatest side of the Triangle ABC

AC is the smallest side of the Triangle ABC

Step-by-step explanation:

from the given figure,

=> ∠B = 50° & ∠C = 60°

we know , ∠A+∠B+∠C = 180°

          => ∠A + 50°+60° = 180°

          => ∠A + 110° = 180°

          => ∠A  = 180° - 110°

          => ∠A  = 70°

so,

∠A  = 70° is the greatest angle => the side opposite to it will be the greatest side of the triangle

i.e., BC is the greatest side of the Triangle ABC

and

∠B  = 50° is the smallest angle => the side opposite to it will be the smallest side of the triangle

i.e., AC is the smallest side of the Triangle ABC
