an isosceles triangle is a triangle with two twin sides, and therefore two twin angles.
if one angle is 98°, well, we can't have another 98° angle because that makes 98+98 = 196°, and the sum of all interior angles in a triangle cannot be more than 180°.
so the other remaining angles must be the twin smaller angles, namely 180 - 98 = 82, and each twin takes half of that, namely 41°.
Check the picture below.
Answer:
The graph of is:
*Stretched vertically by a factor of 3
*Compressed horizontally by a factor
*Moves horizontally units to the rigth
The transformation is:
Step-by-step explanation:
If the function represents the transformations made to the graph of
then, by definition:
If then the graph is compressed vertically by a factor c.
If then the graph is stretched vertically by a factor c
If then the graph is reflected on the x axis.
If The graph moves horizontally b units to the left
If The graph moves horizontally b units to the rigth
If the graph is stretched horizontally by a factor
If the graph is compressed horizontally by a factor
In this problem we have the function and our parent function is
The transformation is:
Then and
and
Therefore the graph of is:
Stretched vertically by a factor of 3.
Also as the graph is compressed horizontally by a factor
.
Also, as The graph moves horizontally
units to the rigth
