89.04 is 84% of 106
106*.84=106
Answer:

Step-by-step explanation:
Given that, a <em>regular octagon </em>is to be constructed.
To find:
Each angle in the octagon = ?
Solution:
We know that a regular triangle (polygon with 3 sides) has an interior angle of
.
And a regular quadrilateral (square) has an interior angle of
.
Therefore, formula for interior angle of a regular polygon with
number of sides can be given as:

For an octagon, we have
.
Value of Interior angle in a regular octagon:

Kindly refer to the attached image for the angle of 
I'm not sure I'll DM u when I get it
Answer: First option.
Step-by-step explanation:
You can use the inverse tangent function to find the value of the angle T:

You can identify in the figure that:

Then, knowing these values, you can substitute them into
.
Therefore, you get that the value of the angle T rounded to the nearest degree is:

This matches with the first option.
Simplify the expression.
