Nathan drew a right triangle with vertices A(x1, y1), B(x2, y2), and C(x3, y3). AC is the longest side in ΔABC. What must be true for this triangle?

For making this statement true we have to check Triangle Inequality theorem.

Step-by-step explanation:

Given that,

Triangle ΔABC having three vertices are A (), B(), C () and AC is the longest side.

from the question,

Diagram of the given scenario is shown below,

According to Triangle Inequality theorem states that sum of any 2 sides of a triangle is always greater than third side.

Taking the ΔABC we have,

This condition must be satisfied for drawing a triangle if any two side sum is lesser than third side it will not form a triangle.

 Hence,

For making this statement true we have to check Triangle Inequality theorem.                                          

which expression can be used to convert 80 us dollars (usd) to australian dollars (aud)?

1 usd = 1.0343 aud

1 aud = 0.9668 usd

step-by-step explanation:

sorry just need the points

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
