☆<A+<C=180°

2<A+30°=<C

<A+2<A+30°=180°

3<A+30°=180°

3<A=180°-30°=150°

<A=150/3=50°

<C=180-50=130°

▪Da recent aayi nee ask cheytha oru questioninu enik complete aayi answer cheyyan pattiyilla.. athinte question njan attatch cheyyunnund...athinte answer below kodukkunnu:

i)We know that, if the line from an angle of a triangle which is perpendicular to the opposite side meets the opposite side at its midpoint ,then the triangle is isosceles

As per this,the given triangle ABC isosceles

Then,AB=AC=10cm

ii) Perimeter=AB+AC+BC=10+10+(6+6)

=32cm

iii)Area= 1/2bh

height=AD

Using pythagoras theorem,

AD=root of AB^2-BD^2=root 10^2-6^2=root 100-36= root 64 = 8cm

Area=1/2bh=1/2×12×8= 6×8 = 48sq.cm
