Question

Solve it please.......................... ​

Answer 1

Answer:

angle adb=90-43 =47(diameter subtends 90degree at the circle

similarly angleabc=90,so ABC is a triangle 52+90+angle bac=180degree

bac=58degree

angle ABC =90degree

Answer 2

Answer:

i) 52⁰

ii) 43⁰

iii) 84⁰

Step-by-step explanation:

i) angle ACB = angle ADB = 52⁰ [ angles in same segment are equal]

ii) angle BDC = angle BAC = 43⁰ [ angles in same segment are equal ]

iii) angle ABC = 180⁰- angle BDC [ sum of opposite angles in a cyclic quadrilateral are 180⁰]

I used the hint given...it was not mentioned that AC and BD are diagonals...so I used the hint given...

Hope it helps...
