"<span>two angles are complementary;" that means the sum of two angles is 90. Since the sum of all three is 180, the last angle is 90. It is a right triangle.
"</span><span>two angles have equal measure;" we can't have two angles which are 90, so the other two are equal. But they sum to 90, so what number plus itself is 90? 45+45=90. We know now that the triangle has measures 45, 45, and 90.
We know that the legs of the triangle are the same, so we can use the Pythagorean theorem to show that </span>
, where h is the length of the hypotenuse and l is the length of the legs.
Of course, this means
. But "<span>the shortest side is half the length of the longest side</span>"! No triangles like this exist.
The only true statement is D

The standard deviation of both the data are the same which is 3.67 and adding the same constant c to each data value results in the standard deviation remaining the same.
<h3>What is the standard deviation?</h3>It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.
We have a data set:
8, 16, 14, 8, 16
As we know the formula for standard deviation is:
Here σ is the standard deviation
xi is each value from the data set
X is the mean of the data set
n is the number of observation in data set.
X = (8+16+14+8+16)/5 = 12.4
n = 5
After calculating the standard deviation will be:
σ = 3.67
Add 8 to each data value to get the new data set 16, 24, 22, 16, 24.
New standard deviation:
σ(new) = 3.67
The standard deviation of both the data are same we can say the standard deviation does not change when we add a constant to each data value.
Adding the same constant c to each data value results in the standard deviation remaining the same.
Thus, the standard deviation of both the data are the same which is 3.67 and adding the same constant c to each data value results in the standard deviation remaining the same.
