In the given figure `triangle`ABC side AC has been produced to D. `angleBCD = 125^(@)` and `angleA:angleB= 2 : 3`, find the measure of `angleA` and `angleB`

In the given figure angleA= 40^(@) . If bar(BO) and bar(CO) are the bisectors of angleB and angleC respectively. Find the measure of angleBOC .

If in triangleABC a=2b and angle A=3 angleB then angleA=

In the adjacent figure, ABC is a triangle in which angleB = 50^(@) and angleC = 70^(@) . Sides AB and AC are produced. If ‘z’ is the measure of the angle between the bisectors of the exterior angles so formed, then find 'z'.

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