Draw the DE ray away from the BAC angle is the next step to copy the BAC angle
<h3>Further explanation </h3>Angles can be formed from two ray lines that have the same starting point
Commonly used terms include foot angle, corner point, and angle size
The magnitude of the angle is usually expressed in degrees
Naming angles can be with one letter according to the vertex or with three letters with the vertex placed between two other letters
There are several steps used to copy the BAC angle:
- 1. Draw the DE line
- 2. Draw a circle using the circle tool with center A. The circle will intersect the lines BA and BC at points F and G
- 3. Use the segment tool to create a segment from the circle radius that has been created
- 4. Use the Compass tool and select the segment from the AG radius
- 5. Make a circle with center point D, with the same radius as AG
- 6. Mark the intersection of the circle with the intersection of the DE as H
- 7. Create the FG segment, and use the compass tool to select the FG segment
- 8. Create a circle with center H, which will intersect the circle with center D earlier at the point I
- 9. Draw the DI line
Then the BAC is congruent to the HDI

Answer:
42.22% probability that the weight is between 31 and 35 pounds
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
What is the probability that the weight is between 31 and 35 pounds
This is the pvalue of Z when X = 35 subtracted by the pvalue of Z when X = 31. So
X = 35
has a pvalue of 0.5557
X = 31
has a pvalue of 0.1335
0.5557 - 0.1335 = 0.4222
42.22% probability that the weight is between 31 and 35 pounds
