<span>To find the greatest perfect square that is a factor of 396, first we check what are the factors of 396 Factors of 396 are: 1,2,3,4,6,9,11,12,18,22,33,36,44,66,99,132,198,396 Now we check which is the greatest perfect square in these. 396, 198, 132, 99, 66,44 are not perfect square, so 36 is the largest perfect square from the factors of 396, 6 x 6 = 6</span>² = 36
It is a right triangle, the right angle is at the point (-3, 5)
Step-by-step explanation:
The first step is to locate the points of the vertices in a plane, in this case they are (0.10), (-8.8) and (-3.5). The desmostration of this is shown in the attached image.
As we can see it is formed a right triangle (the figure outlined in red), and the rigth angle is the one at the point (-3,5).
