What is the value of x? enter your answer in the box. x =

The value of x is 9.

Step-by-step explanation:

In order to find the value of x, we have to note that this is an equalateral triangle. Since all the sides are the same, that also means that all of the angles are the same. This means each angle is equal to 60 degrees. Knowing that, we can set the bottom left corner equal to 60 in order to find the value of x.

7x - 3 = 60

7x = 63

x = 9

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.
