Answer:
C. 39°
Step-by-step explanation:
The measure of the angle where the chords cross is the average of the measures of the subtended arcs.
x = (AB +CD)/2 = (28° +50°)/2 = 78°/2
x = 39°

Answer:</u></h2>
7m^2 - 11m - 2
<h2><u>
Step-by-step explanation:</u></h2>
Distribute the negative.
4m^2 - m + 2 + 3m^2 - 10m - 4 = ?
Now, add the like terms.
4m^2 + 3m^2 = 7m^2
-m + (-10m) = -11m
2 + (-4) = -2
7m^2 - 11m - 2
321 times 23 is 7,383
3,829 divided by 1,221 is (rounded to the nearest hundredth) 3.14
(the real number was: 3.13595414)
