Answer:
AC ≈ 12.9 cm
Step-by-step explanation:
Using the ratio
sin40° =
Multiply both sides by 20
20 × sin40° = b, hence
AC = b = 20 × sin40° ≈ 12.9

we know that
A quadrilateral is called Cyclic quadrilateral <span>if its all vertices lie on the circle.
</span><span>The opposite angles of a Cyclic - quadrilateral are supplementary
</span>so
∠A+∠C=180°
and
∠B+∠D=180°
therefore
the answer is
<span>C) The sum measure of ∠B and ∠D equals 180°</span>
