Answer 1

Step-by-step explanation:

In the adjoining figure, I is the incentre of triangle ABC. AI produced

meets the circumcircle of triangleABC at D. If angle ABC = 52° and

angle ACB = 78°, find the measures of:

(i) angleBCD

(ii) angleCBD

(iii) angleDCI

(iv) angle BDC

(v) angleBIC.

Answer (III)

Answer 2

Answer:

So∠BCD,∠CBD,∠DCI&∠BIC are 30 ,30 ,62.5 &120 respectively....
