Answer:
Polygon: A polygon is a simple closed curve entirely made up of line segments.
1. As starting from triangle
Three kind of triangles: Isosceles, Scalene , and equilateral triangle
In none of these measure of an exterior angle at the vertex of the triangle equals the measure of the adjacent interior angle.
2. Quadrilateral = Parallelogram, Rhombus, Rectangle, Square, Kite, Trpzm
Apart from Rectangle and Square none other quadrilateral have The measure of an exterior angle at the vertex of the quadrilateral equals the measure of the adjacent interior angle.
we can also consider other polygons also like pentagon,hexagon,heptagon.
Decagon and found that it is not always possible that measure of an exterior angle at the vertex of a polygon equals the measure of the adjacent interior angle.
So, the correct option is Sometimes.
I dont see any diagram can you put the diagram

Answer: a) y = - 3/2 x + 7/2
Step-by-step explanation:
The equation of a straight line can be represented in the slope-intercept form, y = mx + c
Where c = y intercept
m represents the slope of the line.
m = (y2 - y1)/(x2 - x1)
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
The line passes through (3, - 1) and (- 1, 5),
y2 = 5
y1 = -1
x2 = - 1
x1 = 3
Slope,m = (5 - - 1)/(- 1 - 3) = 6/- 4 =
- 3/2
To determine the y intercept, we would substitute x = 3, y = - 1 and m= - 3/2 into y = mx + c. It becomes
- 1 = - 3/2 × 3 + c
- 1 = - 9/2 + c
c = - 1 + 9/2
c = 7/2
The equation becomes
y = - 3x/2 + 7/2
Answer:
f⁻¹(x) = eˣ / 3
Step-by-step explanation:
f(x) = In(3x)
y = In(3x)
swap x and y: x = In(3y)
solve y: eˣ = 3y
y = eˣ / 3
f⁻¹(x) = eˣ / 3
