angleBAC:angleABC:angleACB = What?

The triangle ABCis inscribed in a circle, AX, BY and CZ of the angles angle BAC, angle ABC and angle ACB , intersect at the point X,Y,Z on the circle respectively. Prove that AX is perpendicular to XZ.

Sum of the three angles of a triangle ABC is 180^o . The ratio of angle angle BAC , angleABC and angle ACB is 3 : 5 : 10 . If the value of angle BAC is decreased by 10^@ and the value of angle ABC is increased by 10^o . calculate the new ratio of the three angles

Delta ABC is inscirbed in a circle, the bisector of the angles angle BAC, angle ABC and angle ACB intersect at the point X,Y,Zon the circle repectively. Prove that in Delta XYZ , angle YXZ=90^(@)-(1)/(2) angle BAC

In right angled triangle ABC, angleB is right angle. If AB= 8sqrt3cm and BC = 8cm, then find the value of angleACB and angleBAC .

If the bisector of angle A of triangle ABC makes an angle theta with BC, then sin theta is

In Delta ABC , If angle C = 3 angle A, BC = 27, and AB =48 . Then the value of AC is ______

In triangle ABC, angle B is right angled, AC=2 and A(2,2), B(1,3) then the length of the median AD is

In Delta ABC,AB= AC, BE and CF are resepectively the bisectors of angle ABC and angle ACB and itersect the sides AC and AB at the points E and F resepectively. Then four points B,C,E,F are not concylic.
