Answer:
sum: 7.3 difference:2.7
Step-by-step explanation:
Answer: Infinite
Step-by-step explanation:
We know that in a triangle the sum of all the interior angles must be 180°.
The given angles 50º, 90º and 40º
The sum of the angles 50º+ 90º + 40º= 180°
Thus, a triangle is possible with the given measurement.,
Let there is another triangle with the given angles, then by AAA similarity criteria they are similar.
Similarly, all the triangles with the same measurements of the angles must be similar.
Therefore, there are infinite number of triangles can be possible with angles measuring 50º, 90º, and 40º.
From angle bisector theorem, we know that:
Moreover:
so:
and
Yes it is a function
Y=x(x-1)
X(x-1)
X to the 2nd power -1x
