A+b+c=130
a,b,c ip cu 2,3,4
2a=3b=4c=k
a=k/2
b=k/3
c=k/4
k/2 + k/3+ k/4= 130 aducem la acelasi numitor (12)
6k+4k+3k=1560
13k=1560
k=120
a=120/2=60
b=120/3=40
c=120/4=30
12.8 degrees
sin = o/h
sin(x) = 12/54
sin^-1 (12/54)
= 12.8 degrees
NOT SHUUUUUUUUURRRRREEEEEEE
Hi!!!! I think the answer is B or D! Have a nice day!!
