Question

Please answer !!!!!!!!!!!!!!

Answer 1

ST = 63
TU = 63
SU = 126

If T is a midpoint, then it marks the halfway point on the line segment. Therefore, two new line segments are created, and they have equal lengths. Set up an equation where the values are equal to each other and solve for x. Then solve for each length.

Answer 2

ST = 63

TU = 63

SU = 126

Explanation:

Given that T is the midpoint...

Thus TS = ST and SU = 2ST =2TU

from equation...

9n = 5n + 28

9n - 5n = 28

4n = 28

n = 7

Put the value of n in the equation...

ST = 9n

= 9 x 7

= 63

SU = 9n + 5n + 28

= (9 x 7) + (5 x 7) + 28 = 126

Hope this helps!
