Question

In the figure given below, O is the centre of the circle. Find the value of x + y.

Answer 1

Answer:

250

Step-by-step explanation:

x = 125

angle at the centre is double of angle at circumference

so therefore y is also equal to 125

125+125 = 250

Answer 2

Answer:

250degrees

Step-by-step explanation:

angle x=1/2 reflex of angle FOD

(The angle subtended by an arc at the center is double the angle subtended by it at any point on the remaining part of the circle)

angle x=1/2(70+70+110)degrees

anglex=125 degrees

similarly, angle y is equal to angle x by using a similar process.

then,

anglex+angley=125+125=250degrees
