Arc BGD is inscribed by angle BAD and

angle BCD .

Answer 2

Step-by-step explanation:

(1+ cotA — cosecA)(1+ tanA + secA)

1 + cotA — cosecA + tanA + cotA tanA — cosecA tanA + secA + cotA secA -cosecA secA

1 +cotA — cosecA + tanA +1- secA + secA+ cosecA — cosecA secA

1 +(cotA + tanA) +1 — cosecA secA

2 + cosecA secA — cosecA secA
