Question

Find the value of x ,if AB is parallel to CD and BC is parallel to DE and angle BCD is equal to 2x

Answer 1

Answer:

given:

ab is ll cd

bc is ll de

if angle bcd =2x

find x?

we know that some of angles in a triangle=180

angle c=2x

angle b&d=x

therefore x+x+2x=180

4x=180

x=180/4=45

x=45,x=45,2x=90

is a right angle triangle
