Answer:
t = 8; u = 14.
Explanation:
If the two triangles are to be congruent, their side lengths and angles must be equal.
In this case, segment RQ corresponds with segment HI, and segment QS corresponds to segment IJ.
Since they are equal, we know that...
3u = u + 28
and
16t - 32 = 12t
Solve for both!
3u = u + 28
2u = 28
u = 14
16t - 32 = 12t
4t = 32
t = 8
So, t = 8 and u = 14.
Hope this helps!
