ఉపయోగించిన ఫార్ములా:

sin 60°  = \(\frac{\sqrt{3}}{2}\) 

tan 45° = 1

లెక్కింపు:

దానిని బట్టి,

sin (A + B) = \(\frac{\sqrt{3}}{2}\)

⇒ sin (A + B) = sin 60° 

∴ A + B = 60°   ----(1)

అలాగే, ఇవ్వబడింది

tan (A – B) = 1 

⇒ tan (A – B) = tan 45°

∴ A – B = 45°  ----(2)

సమీకరణం (1) మరియు (2) కలుపుతోంది

2 A = 105

A = 52.5

సమీకరణం (1) నుండి మనం పొందుతాము

B = 7.5
