Answer:

The length of TU is 8 units.

Step-by-step explanation:

In triangle XST and triangle XUT,

[tex]\angle SXT=\angle UXT[/tex]                    (Given)

[tex]\angle XST=\angle XUT=90^{\circ}[/tex]              (Given)

[tex]\angle XT=\angle XT[/tex]                          (Common side)

By AAS postulate,

[tex]\triangle XST\cong \triangle XUT[/tex]

Now,

[tex]\angle ST=\angle UT[/tex]                    (CPCTC)

[tex]3x+2=7x-6[/tex]

[tex]8=4x[/tex]

[tex]2=x[/tex]

The value of x is 2.

[tex]TU=7x-6[/tex]

[tex]TU=7(2)-6[/tex]

[tex]TU=8[/tex]

Therefore the length of TU is 8 units.
