Question

Find the area of triangle abc given that abc equals to see a b = 245 degree ac equals to 8 cm

Answer 1

Given angleabc=anglecab=45°
ac=8cm
therefore anglebca=90°
then that triangle is an isosceles right angled triangle
therefore two sides are equal they are ac and bc since if two angled are equal then there opposite sides also equal
then area =1/2by
=1/2*8*8
=4*8
=32squarecm
