The measure of the angle formed by 2 chords that intersect inside the circle is 1/2 the sum of the chords' intercepted arcs.
m∠RST = (143+33)/2 = 176/2 = 88°
The point (−3, 0) is on the x axis.
I know because the point show us that
X=-3 and y=0
That means that the point that we will graph is on the -3 of the x axis. We don’t have to worry about the y because it’s equal to 0.
V+F-E=2
F-E=2-V
-E=2-V-F
E=-2+V+F
