Step-by-step explanation:
I think you copy/pasted parts of different questions together.
but the same principles as in the previous question applies.
I assume you mean here:
find X, RT, TQ, RQ if T is the midpoint of RQ.
as in the previous question "midpoint" means that both sides of the midpoint are equally long.
and therefore we know
8x + 2 = 3x + 7
5x + 2 = 7
5x = 5
x = 1
RT = 8x + 2 = 8×1 + 2 = 8 + 2 = 10
TQ must be the same, but let's check :
TQ = 3x + 7 = 3×1 + 7 = 3 + 7 = 10
correct.
RQ = RT + TQ = 10 + 10 = 20
