In the figure, δabc ~ δdef. solve for x. triangles abc and def. angles b and e are congruent and measure 160 degrees. ab measures x. bc measures 16. de measures 3. ef measures 8.

a. x = 1.5
b. x = 6
c. x = 4
d. x = 5.5

In the given figure ΔABC is similar toΔDEF.Angles B and E are congruent, then their corresponding sides will be in proportion according to S A S similarity.

∠B=∠E=160degrees

AB×EF=BC×DE

X×8=16×3

X=48÷8=6

There fore answer is option B.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
