Answer 1

Răspuns:

a) m(A) +m(B)=180°    m(A)= 5*m(B)

5m(B)+m(B)=180   6m(B)=180   m(B)=30°

m(A)=180-30= 150 °

b) m(A) +m(B)= 90°  m(A)=m(B):3  => m(B)= 3*m(A)

m(A)+3m(A)=90   4m(A)=90  m(A)=90:4=22°30'

m(B)= 67°30'

c) m(A)+m(B)=90   m(A)=m(B)+40

m(B)+40+m(B)=90   2m(B)=90-40= 50

m(B)=50:2 =25°  m(A)=40+25=65°

d)m(A)+m(B)=90   m(A)=m(B)-26

m(B)-26+m(B)=90   2m(B)=90+26= 116

m(B)=116:2= 58°   m(A)= 58-26=32°
