408=1/2(b)(17) how do i solve this?

The correct answer should be 48.

Step-by-step explanation:

To figure this out, simply divide 408 by 17 first to get 24. Since we are doing half of b, we need to do the inverse and multiply 24 by 2 to get b. 24 x 2 is 48. The equation in its form would now be 408=1/2(48)(17).

1/2 x 48 = 24

24 x 17 = 408.

So therefore, 48 is the correct answer.

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

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.
