Answer:
More than one triangle
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent
In a triangle the sum of its internal angles must be equal to degrees
In this problem
The sum of the internal angles is equal to
so
By the sum of the internal angles, we can construct a triangle
but
By the length of the sides keeping the same internal angles, we can construct infinite similar triangles

Answer: 8.3
Step-by-step explanation:
To find the variance, you want to find the mean of the data.
Now that we have the mean, we find the difference between each data point and the mean.
3-5=-2
3-5=-2
8-5=3
1-5=-4
9-5=4
6-5=1
With the difference, you square each and find the average.
(-2)²=4
(-2)²=4
3²=9
(-4)²=16
4²=16
1²=1
The variance is 8.3.
