Answer: 10
----------------------------------------------
Explanation:
Segment TU must be congruent (equal in length) to segment UV in order for the angle TSV to be bisected by segment SU
Bisected = cut in half
So because TU = UV, we can say,
TU = UV
3x+18 = 4x+8
3x+18-3x = 4x+8-3x
18 = x+8
18-8 = x+8-8
x = 10
Well A should be congruent to S because (Base Angles Therom)
A =S
1:4 and 6:24 because 3/3=1 and 12/3=4 and 6/2=3 and 24/2=12
