Answer 1

Step-by-step explanation:

$\huge\underline\purple{Answer}$

Given

$m<IDJ=30° \\ m<HIJ=105°$

To find:-

x (m <FDJ)=?

Solution:-

Here FGHIJ is a octagon

and all sides are equal

$\implies{FJ=JI=IH=GH=FG}$

$\implies{triangle\:AFJ=triangle\:IDJ(because\:FJ=IJ)}$

Again

$m<JID+m<JIH=180°$

$\implies{m<JID=180°-m<JIH} \\ {=180°-105°} \\{=75°}$

in triangle JID

$\large{\boxed{m<IDJ+m<JID+m<IJD=180°}}$

$\implies{m<IJD=180-105-39} \\ {=180-144} \\{=36°}$

$m <IJD=m <FJA(transparent angle)$

$\implies{m <FJA=36°}$

hence x=36°

Hope it help you
