They can form the Triangle
But, they can't form right angled triangle, because in that case, largest side should be smaller than the sum of other two........
Answer:

With the confidence level we can find the significance level:

And the value for
. Then we can use the normal standard distribution and we can find a quantile who accumulates 0.1 of the area on each tail and we got:

Step-by-step explanation:
For this problem we have the confidence level given

With the confidence level we can find the significance level:

And the value for
. Then we can use the normal standard distribution and we can find a quantile who accumulates 0.1 of the area on each tail and we got:

AB = 56 because the bigger triangle is 2 times the smaller one.
If point P is reflected over the y-axis then the new point should be (-2, -4).
Yes since 1/8 is equal to 4/32
