Vedclass · Answer

Let Angles are $ightarrow a-3 d, a-d, a+d, a+3 d$

common difference $\Rightarrow 2 \mathrm{d}=10^{\circ} \Rightarrow \mathrm{d}=5^{\circ}$

$ \operatorname{sum} \Rightarrow 4 a=360 $

$ a =90^{\circ} $

so smallest Angle $\Rightarrow a-3 d=90-3 	imes 5^{\circ}=75^{\circ}$

If all interior angle of quadrilateral are in $A.P.$ If common difference is $10^o$, then find smallest angle ? .............. $^o$
