Question

VA ROG AJUTOR URGENT!!!!
Determinati masurile unghiurilor unui triunghi ABC , stiind ca:
a) m(A)=60 de grade; m(B)=40 de grade
b) m(B)=50 de grade; m(C)=70 de grade
c) m(C)=23 de grade si 25 de minute; m(B)=12 grade si 14 min

Answer 1

a) <) C =180 -(60+40 ) =180-100 =80 grade
b) <) A -180 -(50+70 ) =180-120 =60 gr
c) <)A =180 - (23gr 25' +12gr 14' ) =180 - 35 gr 39 ' =144 gr 21'
