Answer 1

x = 4

Step-by-step explanation

Before, we begin solving, it will be helpful to make a quick sketch of the situation.

BD bisecting means that it divides

Therefore:

=> 7x - 10 = 4x + 2

Solve for x by collecting like terms:

=> 7x - 4x = 10 + 2

3x = 12

x = 12 / 3

x = 4

That is the value of x.
