Question

ONLY FOR GENIUS...
In the figure,O is the centre of the circle,then the value of 2x+y+z is????.......if u answer this u are a born genius:-)

Answer 1

hlo

your answer is

( B ) 390°

angle AEC = angle ADC ( angle in same segment )

y = 30°

angle AOC = 2angle ADC

angle AOC = 2 × 30 = 60°

z = 60°


as , ABCD is a

B + D = 180
B + 30 = 180
B = 150

x = 150°

2x + y + z =

150 ×2 + 30 + 60

300 + 30 + 60

==!= 390✔✔✔




hope it helps..
