Question

13. Diferenta a 2 unghiuri adiacente complementare este :

30 grade 40 minute 20 secunde.


Determinati masurile acestor unghiuri.


Multumesc anticipat!!

Answer 1

m( <A)+m(<B)=90  grade => m(<B)=90-m(<A)

m( <A)-m(<B)=30 grade 40’20”

m(<A)- [90-m(<A)]= 30 grade 40’20”

2m(<A)= 30 grade 40’20”+90 grade

m(<A)=120 grade 40’ 20” :2

m(<A)=60 grade 20’ 10”

m(<B)=90 grade -60 grade 20’ 10”

m(<B)=89 grade 59’60”- 60 grade 20’ 10”

m(<B)=29 grade39’ 50”

R: m(<A)=60 grade 20’ 10”

    m(<B)=29 grade39’ 50”
