Using the defects method, which of these relationships represents the Law of Cosines if the measure of the included angle between the sides a and b of ∆ABC is more than 90°?a.area of square c2 = -area of square a2 – area of square b2 + area of defect1 + area of defect2
b. area of square c2 = area of square a2 + area of square b2 + area of defect1 – area of defect2
c. area of square c2 = area of square a2 + area of square b2 – area of defect1 – area of defect2
d. area of square c2 = area of square a2 + area of square b2 + area of defect1+ area of defect2
e. area of square c2 = area of square a2 - area of square b2 + area of defect1 - area of defect2

Answers

Answer 1
Answer: "area of square c2 = area of square a2 + area of square b2 – area of defect1 – area of defect2" is the one relationship that represents the Law of Cosines if the measure of the included angle between the sides a and b of ∆ABC is more than 90°. The correct option among all the options that are given in the question is option "c".
Answer 2
Answer:

Answer: c. area of square c2 = area of square a2 + area of square b2 – area of defect1 – area of defect2

(Option C)

Explanation:

The cosine rule helps to determine the different angles and sides of a triangle. The cosine rule is helpful when you need to find the third side of the triangle when the other two sides of the triangle are given  and the angle between them.

What would most likely occur if an experimental design specifies only a test group?a)The experiment will lack a control.
b)The experiment will lack a purpose.
c)The experiment will not be repeatable.
d)The experiment will not have variables.

Answers

Answer;

The experiment would lack a control group

Explanation;

-An experiment deliberately imposes a treatment on a group of objects or subjects in the interest of observing the response.

-Experimental design involves taking time and effort to organize the experiment properly to ensure that the right type of data, and enough of it, is available to answer the questions of interest as clearly and efficiently as possible.

-A scientific control is an experiment or observation designed to minimize the effects of variables other than the independent variable. This increases the reliability of the results, often through a comparison between control measurements and the other measurements.
"The experiment will lack a control" is the one among the following choices given in the question that would most likely occur if an experimental design specifies only a test group. The correct option among all the options that are given in the question is the first option or option "a". I hope the answer has helped you.
