Answer:
89.0°
Step-by-step explanation:
The segment from the centre of the circle to the chord is a perpendicular bisector, hence
third side of right triangle = 12.7 ÷ 2 = 6.35
The angle subtended at the centre by arc CD is twice the angle subtended by the right triangle at the centre
The triangle from the centre to C is congruent to the triangle from the centre to D
Calculate the angle (Θ ) in the right triangle using the sine ratio
sinΘ = 
= 
Θ = 
( ) ≈ 44.5°
Hence
measure of CD = 2 × Θ = 2 × 44.5 = 89.0°

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the
10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

The potential problems with Antonia's simulation is that she over simulated the situation and her conclusion has the misleading data.
<h3>What is the potential problem?</h3>
The potential problems is the simulation or method to analysis what is gone wrong in a particular program.
She sets her chess computer program to play 100 first moves in the game of chess. In this simulation, she only focuses on first move and overstimulated the situation.
Antonia concludes that of the 20 possible opening moves in chess, most players will move the pawn piece in front of the queen forward two spaces.
In this conclusion she has misleading data as each player has different strategy.
Thus, the potential problems with Antonia's simulation is that she over simulated the situation and her conclusion has the misleading data.

The probability of Julia picking 49 is 1/100 ( one number out of 100)
The probability of Shelly picking 49 is also 1/100 ( one number out of 100)
The probability of both picking the same number is
1/100 x 1/100 = 2/100 = 1/50 = 0.02 = 2%
