Line QS is a perpendicular bisector to triangle PQR as pictured below. What is the length of the value of x?

I need an answer ASAP

3

Step-by-step explanation:

Side QP is equal to side QR so 4x-2=10, then just solve for x and you get 3

x=3

Step-by-step explanation:

the trangal is isosoles so both sides need to equal 10 so the equation would be 4x-2=10.

frist you would add both sides by 2

4x-2=10

    +2 +2

4x=12

then you would divide both sides by 4

4x/4=12/4

so your anser should be x=3

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
