Answer:
Step-by-step explanation:
using the formula below, the central angle is 20° (bc 360-180-160=20)
radius is 14 (28/2=14)
Answer:
Line BE = 180 degrees
Therefore, angle BAD + angle DAE = 180 degrees
Angle DAE = 180 -110 = 70 degrees
Step-by-step explanation:
0.31 = 31%
% is out of 100 so 31% is 31 out of 100 which is 31/100 :)
(2,0,-1,-1,-2) that is the domain from what I remember. Hope that help
Answer:
Yi Xing invented the astronomical clock and introduced some new methods of interpolation in mathematics.
Step-by-step explanation:
Yi Xing was both an astronomer and a mathematician during the era. He invented the astronomical clock which was more accurate than the initial water and Sun's clock in use.
Furthermore, Yi Xing also discovered some new methods of interpolation in mathematics of which the meaning and interpretation became controversial. Interpolation is a method majorly in mathematics that can be used to estimate a value of a function from its discrete values. It involves first order differences and second order differences.
Also, Yi Xing was able to design a calendar in A.D. 727.
