Step-by-step explanation:
Please find the image file of the graph.
We know
so because the triangle is isosceles.
when
is called by
.
We know that
since E and D are tangent points to a circle.
They have
since D and F are tangent points only to circle.
Thus, if the perimeter is 32, the following is the result:

Therefore the length of 
Answer:
83°
Step-by-step explanation:
Since angle x and angle y are supplementary angles,
x + y = 180°.
Since y = 97°
x = 180° - y = 180° - 97° = 83°
