telo118 [61]
When you draw a diagonal line from Y to W, you will create two congruent triangles.

Each of these triangles will have three sides of different lengths, making them scalene triangles.

In each of these triangles, there will be one 90° angle, right angle, and two acute angles (less than 90°). This would classify these triangles as right triangles based on the angles.

Both triangles are right, scalene triangles.

Explain why a regular polygon cannot have an interior angle that is 40°.
Minchanka [31]

Answer:

Explained below.

Step-by-step explanation:

The formula for the interior angle of any regular polygon is given as;

Interior Angle = 180(n - 2)/n

Where n is number of sides

We are told the interior angle is 40°

Thus;

180(n - 2)/n = 40

Cross multiply to get;

180n - 360 = 40n

180n - 40n = 360

140n = 360

n = 360/140

n = 2.57

Number of sides of a regular polygon cannot be in decimal nor can it have less than 3 sides.

Thus, a shape with interior angle of 40 cannot be a polygon.
