Question

pls help with math that’s attached

Answer 1

3x+9=7x-17

26 = 4x

x=6.5

TU:28.5

Answer 2

TU = 28.5

Explanation:

The triangles are congruent because of side-angle-side

TU = VU because corresponding sides of congruent triangles are congruent.

so:

3x + 9 = 7x - 17

simplify:

4x = 26

x = 6.5

TU = 3(6.5 + 9) = 19.5 + 9 = 28.5
