Answer:
SU = 36
Step-by-step explanation:
T is the mid point so the distance of ST and TU is the same. Since ST and TU are the same, 7x + 4 = 10x - 2.
Solve for x
7x + 4 = 10x - 2
7x - 10x = - 2 - 4
-3x = -6
x = 2.
Find SU
SU = ST + TU
= (7x + 4) + (10x - 2)
substitute the value for x into the equation (x=2)
[7(2) + 4] + [10(2) - 2] = 36
I hope this helps :)
