Triangles slb and dog are similar with < s=< d and < l =< o. if sl, lb and sb are 3,4,5 respectively and do=5 find og and dg

All the side measures of ΔDOG will have the same relationship to their corresponding ΔSLB measures that DO has to SL.

OG/LB = DO/SL
OG/4 = 5/3
OG = 20/3

DG/SB = DO/SL
DG/5 = 5/3
DG = 25/3

In summary,
  OG = 20/3 = 6 2/3
  DG = 25/3 = 8 1/3

Ithink this answer would be c cause i seen this before

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.
