Answer:
an infinite number
Step-by-step explanation:
The left side of the equation is a restatement of the right side of the equation. It is true for all values of x. There are an infinite number of solutions.
80% converted to a decimal is 80/100=0.8
Multiply the total with the percent 685*0.80
The answer is 540
I think the smallest sides correspond to the smallest angle measurement. So the smallest side would be UT and then VT and then UV.
