Using the quadratic formula we can see the roots are:
3 and -3
It could be radius, circumference, or diameter.<span />
Let's say
![x](https://tex.z-dn.net/?f=x)
is the measure of the first angle and
![y](https://tex.z-dn.net/?f=y)
is measure of the supplement of
![x](https://tex.z-dn.net/?f=x)
. We know that supplementary angles add up to 180°, so
![x + y=180](https://tex.z-dn.net/?f=x%20%2B%20y%3D180)
. We also know that
![x = 29y](https://tex.z-dn.net/?f=x%20%3D%2029y)
. Therefore,
![29y+y=180](https://tex.z-dn.net/?f=29y%2By%3D180)
. It follows that
![y = 6](https://tex.z-dn.net/?f=y%20%3D%206)
, therefore, the first angle is 174° and the second angle is 6°.
Why do I need to type so much? Anyway it’s 7.5
