as we know that angle made on a point I always 360 digree
hence it is given that the one side of angle is 260 digree so the other side of angle obc will be
360 digree - 260 digree = 100 digree
in triangle boc
ob = oc
so it isoscelteral triangle which two side is equal. as we know that the angle of base of isoscelteral triangle is equal so
angle obc = angle ocb
by the formula of sums if triangle
all angle sum is 180
but one angle is 100 digree so the other angle will be 50 digree and 50 digree
and bac is 90 digree because angle made on semicircle is always 90 digree
