AS BCA is isosceles
therefore angles opposite are equal to equal sides
hence BCA = 45
because 2x+ 90 = 180
x = 45
where x= bac=bca
AS bac = 45
hence CAD = 180-45 = 135
therefore angles opposite are equal to equal sides
hence BCA = 45
because 2x+ 90 = 180
x = 45
where x= bac=bca
AS bac = 45
hence CAD = 180-45 = 135
