Question

In the given figure, O is the centre of the circle​

Answer 1

Answer:

yes

d is correct. beacause Angle in a semicircle is 90.

So 90+25+65=180

Hence proved

Answer 2

Hey mate ,

x = 90°. [ Angle made by the diameter at the circle is always 90° ]

In ∆ ABC

x + 25 + y = 180

y = 180-25-90

y = 65°

Thus option ( d ) is correct
