Step-by-step explanation:
combine like turms and rearrange
In this question, it is given that the measurement of angles USW and TSR are 7x-34 and 4x+9 .
First we have to find the relationship between those two angles .
And these angles are vertical opposite angles which are congruent .
Therefore


Therefore measurement of angle USW is

8x + 47 = 8x + 40
No solutions (the above 2 expressions cannot be equal for any value of x)
