Find `/_A`=

In a cyclic quadrilateral ABCD, if m/_A=3(m/_C)* Find m/_A

On a semi-circle with A B as diameter, a point C is taken, so that m\ (/_C A B)=30^0dot Find m\ (/_A C B)a n d\ m(/_A B C)

In fig. 14 , A B C is right-angled at C ,\ a n d\ C D_|_A Bdot also /_A=65^0dot\ Find (i) /_A C D (ii) /_B C D (iii) /_C B Ddot

In DeltaABC , the angle bisectors of /_B "and" /_C meet at O. If /_A=70^(@) , find /_BCO=(1)/(2)/_C .

Fig.17 is made up of two triangles. find /_D A B+/_A B C+/_B C D+/_C D Adot

In parallelogram ABCD, if /_A=75^@ , find /_B .

In fig.30, find (i) /_A C D , (ii) /_A E D

In fig.30, find (i) /_ACD,( ii) /_AED

In A B C , if bisectors of /_A B C\ a n d\ /_A C B intersect at O at angle of 120^0 , then find the measure of /_A

In ABC, if bisectors of /_ABC and /_ACB intersect at O at angle of 120^(@), then find the measure of /_A
