Question

in the given figure find value of y​

Answer 1

Answer:

y=15°

Step-by-step explanation:

see, there are three lines and 3 pair of vertically opposite angles. If you know, vertically opposite angles are equal..so there are four 5y and two 2y.

around a point the angle is 360 degrees. so 4(5y)+2(2y)=360°

so 20y+4y=360°

so 24y=360°

so 4y=60°

so y=15°

Answer 2

Answer:

15°

Step-by-step explanation:

In the given figure,

angleFOA= 5y (vertically opposite angles)

angleMOF+angleFOA+angleDOA= 180 (complmentary angles)

5y+5y+2y= 180°

12y= 180°

y= 180/12

= 15°
