<h3>Since they are vertically opposite angles then we can set the two angles equal to each other.</h3>
<h3>Subtract 30 from both sides</h3>
<h3>Divide both sides by 8</h3>
The formula for the circumference is 2πr.
The diameter d is given, which is 2 times the radius r (d = 2r)
So you have to calculate π d = 3.142×1.8 ≈ 5.7
Answer:
rise/run= -20/5= -4/1=-4 slope
or you sound use the slope formula (y2-y1)/(x2-x1)
(-9-11)/(1+4)
-20/5
-4
