Question

please solve 10 and 11 questions. QUESTIONS ARE IN THE ATTACHMENTS GIVEN BELOW

Answer 1

10) angle BOD =100

by theorem 1/2 angle BOD =angle BAD

SO,

ANGLE BAD =50 .

ANGLE BAD + ANGLE BCD =180

( OPPOSITE ANGLE OF CYCLIC QUADRILATERAL IS 180)

50 + ANGLE BCD=180

ANGLE BCD=180-50=130

ANGLE BCD=130

HERE IS YOUR ANSWER DEAR. PLEASEE MRK MEE AS BRAINLIST

Answer 2

Answer:

50° and 130° respectively

Step-by-step explanation:

∠BAD = ∠BOD ÷ 2 => 100÷2 => 50°

Sum of opposite angles of cyclic quadrilateral are 180°

∠BOD + ∠BCD = 180°

=> 50° + ∠BCD = 180° => ∠BCD= 130°

Hence, Answer is 50° & 130°.
