Answer:
D. 104
Step-by-step explanation:
We know that xy and yz are supplementary to each other
That means they add up to 180
We can set up an equation with this information
(4x+32)+(2x+40)=180
6x+72=180
6x=108
x=18
Now that we know what x is, we can plug it into 4x+32 to find degree of xy
4(18)+32
72+32
D. 104
As they both are tangents of the same circle, their lengths must be equal.
RS = RT
x/4 = x-6.3
x = 4x - 25.2
4x-x = 25.2
3x = 25.2
x = 8.4
As, RS = x/4, it will be equal to 8.4/4 = 2.1
SO, YOUR FINAL ANSWER IS RS = 2.1
The answer is c by process of elimination
