Answer:
160°
Step-by-step explanation:
Minor Arc NR is equal to the measure of its central angle, S.
S and 20 are supplementary angles, so they add up to 180.
So, s +20 =180
S = 160, so NR = 160 as well
You’re answer is c.49
i didn’t have to estimate because 21 times 49 gives you 1,029
Hope this is helpful!!!
50
Since a triangle always equals 180, you add 68 and 62, which gets you 130.
180 - 130 = 50
Hope this helps!
