Answer for the question No.17

$x=28.11\ degree$

$m\angle\ ABC=28.11\ degree$

Step-by-step explanation:

Answer for the question No.17

Given:-

$\angle\ BAD=(5x+10)\ degree$

$\angle\ ADC=(87)\ degree$

$\angle\ DCB=(3x+10)\ degree$

Let, $m\angle\ ABC=x$

In quadrilateral ABCD,

$\angle\ BAD+\angle\ ABC+\angle\ DCB +\angle\ ADC =360\ degree$ ---(sum of angle of quadrilateral is 360 degree)

$\therefore\ (5x+10)+x+(3x+10)+87=360$

9x+107=360

9x=360-107

9x=253

$x=\frac{253}{9}$

$\therefore\ x=28.11\ degree$

SInce x= $m\angle ABC$

$\therefore\ m\angle\ ABC=28.11\ degree$
