PLS HELP. this is due soon,<br> only answer if you actually know it; no guessing for points please

OLga [1]

Answer:

102

Step-by-step explanation:

x = 180 - (4x - 2) - 78

x = 180 - 4x + 2 -78

5x = 180 + 2 - 78

5x = 104

x = $20\frac{4}{5}$ .

So, angle UTW is 4 * $20\frac{4}{5}$ - 2 + $20\frac{4}{5}$ = 5 * $20\frac{4}{5}$ - 2 = 104 - 2 = 102
