Question

if ab || CD .Find the value of x figure given in the pic..​

Answer 1

Answer:

i know the answer. it's 45 degrees.

Step-by-step explanation:

first find the angle acd.

then use the vertically opposite angles property.

then you can find angle ecf.

Now use the Angle sum property of triangles and find X.

180=30+105+X

180-135= X

45= X

Answer 2

Answer:

• AS AB||CD. SO Angle A will be equal to angle DCF. so angle DCF will be 75°. so we can find angle FCE by. DCE+FCE=180°(Linear pair).. so75+FCE=180.

FCE=180-75=105°. SO FCE+30°+X=180°(SUM OF ALL THE ANGLES OF TRIANGLE). X=180-30+105 X=45°. ANS
