Based on the given parameters, the length of c is 8.0 units
<h3>How to determine the side length of c?</h3>
The given parameters are
Angle c = 76 degrees
Side a = 20
Side b = 13
The length of c is then calculated using the following law of sines
c^2 = a^2 + b^2 - 2absin(C)
Substitute the known values in the above equation
So, we have
c^2 = 20^2 + 13^2 - 2 * 20 * 13 * sin(76)
Express 20^2 as 400
c^2 = 400 + 13^2 - 2 * 20 * 13 * sin(76)
Express 13^2 as 169
c^2 = 400 + 169 - 2 * 20 * 13 * sin(76)
Evaluate the product and sin(76)
c^2 = 400 + 169 - 520 * 0.9703
Evaluate the product
c^2 = 400 + 169 - 504.55
Evaluate the exponents
c^2 = 400 + 169 - 504.55
So, we have
c^2 = 64.45
Evaluate the square root
c = 8.0
Hence, the length of c is 8.0 units

Answer:
45 pieces.
Step-by-step explanation:
First, if the ratio is 5 : 4, then is you multiply 4 x 5 to get 20, you need to multiply 5 x 5 to get 25.
Second, 20 + 25 = 45 which is the total amount of puzzle pieces.
Hope this helps!

Answer:
Mean-39.6
Mode- 1,3,76
Median-45
MOC- 45
Step-by-step explanation
I got the mean by adding all of the numbers up and then dividing them by 13.
I got the mode because those numbers occur the most often.
I got the median by putting the numbers in order from least to greatest then picking the middle number.
I got the measure of center because there is not an outlier so you would use the median. If there was an outlier then you would use the mean.
