Răspuns :
{ a,b } d.p { 5,13 }
----------------/------
a + b = 90
-----------------//-----
a / 5 = b / 13 = K
a / 5 = K => a = 5 K
b / 13 = K => b = 13 K
5 K + 13 K = 90
18 K = 90
K = 90 : 18
K = 5
a = 5 x 5 = 25° ( masura primului unghi )
b = 5 x 13 = 65° ( masura celui de-al doilea unghi )

fie B si C, cu masurile b si ,respectiv, c
atunci
b/5=c/13=(b+c)/(5+13)=90°/18=5°
b=5*5°=25°
c=13*5°=65°
as simple as that!!!
