Given: △abc, m∠a=120°, ab=ac=1 find: the radius of circumscribed circle

9514 1404 393

  1

Step-by-step explanation:

Angle B of isosceles triangle ABC is (180° -120°)/2 = 30°, so arc AC of the circumscribed circle has a measure of 2B = 60°. A chord that subtends a 60° arc is the same length as the radius, so the radius is 1.

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
