use the diagram below to answer the following questions.

1. can you use pythagorean theorem to find the missing side? why or why not?

2. would you use law of sine or law of cosine to find the length of side cb? explain your answer.

3. find the length of side cb. show your work and round your answer to the nearest whole number.

4. find the measure of angle c. (hint: use the other “law”). round your answer to the nearest whole degree.

5. what is the measure of angle b? show your work and round your answer to the nearest whole degree.

Try the suggested solution (all the details are in the attached picture).

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
