Question

The measure of a major arc is 270°. What is the measure of the corresponding minor arc
​

Answer 1

Answer:

The major arc subtends angle 2x and the minor arc subtends angle x

Since the length of arcs depend upon the angle subtended at the centre

2x+x=36o(complete angle)

3x=120o×3

x=120o

Hence major arc subtends 240o and minor arc subtends 120o
