The length of both AB and DC is the same.
19 degrees
We want to know the arc measure for the whole circle, except for DC. So, we can subtract the arc measure of DC from 360 to find DBC. Since we found DC above, all we need to do is subtract.
360 - 19 = 341
DBC = 341 degrees
Hope this helps!! :)
Y=-3x+5
the slope is negative because the line is going down from left to right
the y-intercept is 5 because that’s where the line crosses the y-axis
8x+3=43
-3 -3
8x=40
/8 /8
X=5
