**Help please? It closes soon.** Solve for r.

r/16≥8

r≥2

r≤128

r≤2

r≥128

r≥128

Step-by-step explanation:

To solve the inequality, we have to get r by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.

r is being divided by 16. The opposite of division is multiplication, so multiply both sides by 16.

Therefore, the answer is r≥128, or the last choice.

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.
