Question

solve the adjoing diagram

Answer 1

A. (3x + 10) + (3x + 4) +50+=180
=6x + 64= 180
=6x = 180-64
=6x = 116
=x = 116/6

Answer 2

Answer:

$\huge\boxed{\fcolorbox{yellow}{red}{Given:}}$

$ABCD\ is\ a\ quadrilateral.\\</h3><h3>where\ angle\ A=(3x+4) degree\\</h3><h3>angle\ B=(50+x)degree\\</h3><h3>angle\ C=(5x+8)degree\\</h3><h3>angle\ D=(3x+10)degree$

$\huge\boxed{\fcolorbox{yellow}{red}{To find:}}$

value of x=???

value of angle DAB=???value of angle ADB=???

$\huge\boxed{\fcolorbox{yellow}{red}{Solution:}}$

Sum of angle of quadrilateral =360degree..

A/Q

$(3x+4)+(50+x)+(5x+8)+(3x+10)=360\\</p><p>=>3x+x+5x+3x+4+50+8+10=360\\</p><p>=>12x+72=360\\</p><p>=>12x=360-72\\</p><p>=>x=288÷12$

Hence,x=24

angle DAB=3x+4

=3×12+4

=36+4

=40degree

angle ADB=3x+10

=3×12+10

=36+10

=46degree
