Answer 1

Răspuns:

Explicație pas cu pas:

∡ABC=∡BAO+∡CBO=23°+37°=60°

∡BOC=180°-2·37°=106°

∡AOB=180°-2·23°=134°

∡AOC=360°-(106°+134°)=360°-240°=120°

∡ACO=60°

∡C=60°+37°=97°

∡A=23°+60°=83°

b) ∡C=37°+39°=76°

∡BOC=180°-2·37°=106°

∡AOC=180°-2·39°=102°

∡AOB=360°-(106°+102°)=360°-208°=152°

∡ABO=(180°-152°)/2-=14°

∡A=14°+39°=53°

∡B=14°+37°=51°
