Answer:

Step-by-step explanation:

Given x and y vary directly then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition x = 20 , y = 10 then

10 = 20k ( divide both sides by 20 )

$\frac{10}{20}$ = $\frac{1}{2}$ = k

y = $\frac{1}{2}$ x ← equation of variation → C

spin [16.1K]

Answer:

$x=27\degree$

Step-by-step explanation:

$\because AC || DE.... (given)$

$\therefore m\angle CAD= m\angle EDF\\ (corresponding \: \angle s)$

$\therefore m\angle BAD= m\angle EDF\\(\because B\in \overleftrightarrow{AC})$

$\therefore m\angle BAD= 2x\\(\because m\angle EDF=2x)$

$In\:\triangle BAD,$

$m\angle BAD+m\angle BDA+m\angle ABD= 180\degree$

$2x+2x+72\degree = 180\degree$

$4x= 180\degree -72\degree$

$4x= 108\degree$

$x= \frac {108\degree}{4}$

$x=27\degree$
