Question

In fig angle 1 = angle 3, angle 2= angle 4. DE = 4, CE= x+1, AE = 2x+4; BE = 4x-2. Find x​

Answer 1

Answer:

X=3

Step-by-step explanation:

In DEC, & AEC,

angle 1=angle 3,angle2= angle 4,angle DEC=angle AEB

so, both triangles are similar

By AAA rule,

DE/BE=CE/AE

4/(4x-2)=(x+1)/(2x+4)

by cross multiplication, lastly get a quadratic equation,

2xsquare-3x-9=0

solving we get, x=3 , -3/2

taking x=3

Answer 2

Answer:

I hope u get the answer....THANKS .....
