In the smallest of the three triangles (with sides
) we have

In the second-largest triangle (with sides
), the length of the missing side is
. Then in the largest triangle (with sides
), we have



Equivalently, we have

In turn, we find

Answer:
Mean: 13
SD: 
Step-by-step explanation:
To find the mean, you have to add up all of them and divide by the number of them. The sum is 30+30+18 or 78, and there are 6 so the mean is 78 / 6 = 13.
To find the standard deviation, we need to first find the distance from them to the mean. These are 2, 3, 3, 3, 5, and 2. Square these values to get 4, 9, 9, 9, 25, and 4. Now we have to take the mean of this, which is 8+27+25=35+25=60, so the mean is 10 and now we take the square root so the SD is
.

b.?
c. yes it will still be because it is still in y=mx+b formula
Answer:
Infinite number
Step-by-step explanation:
we know that
If one angle is 90°, and another half of that, then it must be 45° and so the third angle is also 45°. (The sum of the internal angles of a triangle must be equal to 180 degrees)
Remember that
If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
therefore
There is an infinite number of unique triangle with these angles.
