Question

In the given figure, / || m. Find the value of x so that the lines AB and CD are parallel.​

Answer 1

Answer:

15degrees

Step-by-step explanation:

if we consider l//m and AB transversal then angle LEF= angle MFB as they are corresponding angles....

now consider AB//CD and m is transversal then angle MFB = angle FHD ...

now 3x-15 and 2x are vertically opposite angles so they are equal

therefore, 3x-15=2x

3x-2x=15

x=15 degrees
