Answer:
165
Step-by-step explanation:
First, m<UTS=m<UTV+m<VTS by Angle Addition Postulate. Then, you substitute all the values that you provided for the angles. 15x+15=x+15+140. You then solve for x.
15x+15=x+155
14x=140
x=10
You then plug back in 10 for X in the value of m<UTS. 15(10)+15=165
Answer: 3.36
Step-by-step explanation: 75minutes / 28= 2.678571428571429
9/2.678571428571429=3.36 times
You didn't attach anything, but this is how you should solve this equation: given an equation
the solutions are

In your case, the values are
. If you plug these values inside the solving formula, you have

So, the two solutions are 1 and 7
