Several studies showed that after eating a low-fat cereal for two meals a day, subjects had lost some weight. a cereal company financed this research. what is wrong with this study?

What is wrong with this study is the because of the self interest study that has been conducted because this is a type of study of which the only participants involved are the ones who want to participate with the experiment, therefore, it wouldn’t be reliable as they don’t have a wide variety of participants in helping the study.

It is questionable that the sponsor is a cereal company because this sponsor can be greatly affected by the conclusion

if triangle abc is congruent to triangle def, their interior angles are congruent, because congruent parts of congruent triangles are congruent (cpctc).

that means ∠d is congruent to ∠a; ∠d is equal to 8x - 2.

interior angles of all triangles add to equal 180 degrees, so you can set the sum of these interior angle values equal to 180 and solve for x.

180 = (8x - 2) + 22 + 72

180 = 8x - 2 + 22 + 72

180 = 8x + 92

88 = 8x

11 = x

x = 11
