Question

Dau coroana! Repede va rog! Exercitiul 2! 45 puncte!!

Answer 1

intr-un triunghi echilateral  toate unghiurile = 60 grade 

a)z = 60 grade ( in continuare - g)
x+34g =60 g
x = 26g
y-15 gr = 60 g
y =75g
b)10 + z = 60
z = 50 grade
y : 2 = 60
y=120 grade
x + 80 =180 - 60
x + 80 = 120
x = 120 - 80
x=40
c) z - 40 = 60
z= 60 + 40 
z = 100 grade
y + 20 = 60
y=60 - 20 
y = 40 grade 
x + y = 60
x+40 = 60
x = 60 - 40 
x = 20 grade
