Question

Doar 11 va rog sa îmi spuneți este urgent dau coroană va rog repedeeeeeeee!

Answer 1

a) m(C)=180°-(42°10'+57°50')=180°-100°=80°

b) m(C)=2*20°20'=40°40'⇒m(B)=180°-(20°20'+40°40')=180°-61°=119°

c) m(A)=180°-(37°41'18"+68°32'42")=180°-106°14'=179°60'-106°14'=73°46'

Answer 2

∡A+∡B+∡C=180°

a) ∡A+∡B=42°10'+57°50'=99°60'=100°

∡C=180°-100°=80°

∡C=80°

b) ∡C=20°20'×2=40°40'

∡A+∡C=20°20'+40°40'=60°60'=61°

∡B=180°°-61°

∡B=119°

c) ∡B+∡C=37°41'18''+68°32'42''=105°73'60''=105°74'=106°14'

∡A=180°-106°14'=179°60'-106°14'=73°46'

∡A=73°46'
