Question

GEOMETRY. NEED HELP NOW PLEASE!!

Answer 1

So here we go, lines OA and OB are radii of the circle O
since the measurement of ∡ O is given it is easy to find the other measurements.
180-85 = 95°  (all the sides of a triangle = 180°)
That angle divided by two
$\frac{95}{2}$ = 47.5°
We know that the radii are the sides which makes that triangle isosceles.
So m∡BAC = 47.5°
Answer is B)47.5

Answer 2

They have already given you d. 360 divided by 2 is your answer
