Question

5. Angles B and C of a A ABC are 30° and 60° respectively,
State which of the following is/are 'True'
(i) AB2 + AC2 = BC2 (ü) AB + BC2 = AC2
(i) AC2 + BC2 = AB2
​

Answer 1

Answer:

option (i) is correct

if B=30° and C=60° and using angle sum property we get, A=90° i.e. triangle is right angled at A

therefore, using Pythagoras theorem, we get

AB^2+AC^2=BC^2
