Ina `Delta ABC, angle ABC=90^@ and angle ACB=30^@` then find `AB:AC`.

I is the incentre of Delta ABC, angle ABC=60^(@) and angle ACB=50^(@) . Then find angle BIC .

In the figure , AC =12 cm , angle ABC =90 ^@ , angle BAC=30^@ , then find AB and BC.

(iv) In Delta ABC, angle ABC=90^@ and if AB=6 cm and BC= 8 cm , then find circum-radius of DeltaABC .

In a Delta ABC, angle A=90^(@), angle B=30^(@) find the ratio of sides .

In a Delta ABC, AB=12cm, angle ABC=30^(@), angle ACB=45^(@) find the area of Delta ABC .

In Delta ABC, angle B = 90^(@), angle C = 30^(@), AB = 6 cm then AC =….

If triangle ABC , angle B = 90^@ . If AB = 12, angle C = 30^@ . Then find BC.

In Delta ABC , right-angled at B. AB = 5 cm and angle ACB =30^@ (see Fig. 8.19). Determine the lengths of the sides BC and AC.

In Delta ABC , right angle is at B,AB = 5cm and angle ACB =30^(@) Determine the lengths of the sides BC and AC.
