What is the last step in converting 486,300,000,000,000,000,000 to a scientific notation? Determine the exponent is 4.863.

Determine the coefficient is 4.863.

Determine the coefficient is 20.

Determine the exponent is 20.

answer:

c. the third graph

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.
