What is the location of the point on the number line that is 2/9 of the way from a = 5 to b = 23

From 5 to 23, there are 18 units, 23 - 5 is just 18, so the segment AB is 18 units long.

now, this point is 2/9 of the way hmmmm what is 2/9 of 18?  well, is just their product,   

so the point is 2/9 of the way from A, namely, is 4 units away from 5, 5+4.

An obtuse triangle.

Step-by-step explanation:

We have given the different sides of a triangle that is Side A = 2, Side B = 8 and Side C = 7.

According to the question, we can tell the triangle is acute, obtuse or a right triangle.

We know that,    

For given sides x,y,z of a triangle,

If = , then its a right triangle.

If < , then its an acute triangle.

If > , then its an obtuse triangle.

We have a = x = 2, b = z = 8 and c = y = 7.

Note: We always take z as the greatest side length.

Now,

We can see that, 4 + 49 < 64.

So, we can apply rule

if > , then its an obtuse triangle.

Therefore,

Given sides are of an obtuse triangle.
