Question

calculate the value of angle X, angleY and angle Z​

Answer 1

Answer:

We know that in a circle there is 360° angle

so, 6x +6x +4z+ 4z+ 8y + 8y = 360

12x + 8z + 16y = 360

4( 3x + 2z + 4y ) = 360

3x+ 2z+ 4y = 360/ 4

3x + 2z + 4y = 90 ....----(1.). × 2

6x + 4z + 8y = 180 ( linear pair ) -------(2.)

6x + 4z = 90°

So, 90° + 8y = 180

8y = 180/ 90

8y = 90

y = 90 / 8 = 11.2°
