Answer:
The length of segment XY can be found by solving for a in
The measure of the central angle is
.
Step-by-step explanation:
If the regular octagon has a perimeter of 122.4cm, then each side is
The measure of each central angle is
The angle between the apothem and the radius is
The segment XY=a is the height of the right isosceles triangle.
We can use the Pythagoras Theorem with right triangle XYZ to get:
Therefore, the correct options are:
The length of segment XY can be found by solving for a in
The measure of the central angle is
.
y = 11/21
To solve this first evaluate the power (then calculate the sum):
<u><em></em></u>y - <u><em>
</em></u> = 5y +<u><em> (-5 + 7)</em></u>
16y - 9 = -5y + 2
Next Move terms (move variable to the left side and change its sign) (Move constant to the right side and change its sign):
16y <u><em>- 9 </em></u>= <u><em>-5y</em></u> + 2
16y + 5y = 2 + 9
Next Collect the like terms and calculate the sum:
<u><em>16y + 5y</em></u> = <u><em>2 + 9</em></u>
21y = 11
Lastly divide both sides of the equation by 21:
<u><em>21y = 11</em></u>
y =
Points, lines, planes are all undefined terms of geometry
<h3>Point S line in plane H</h3>To do this, we draw a plane H (represented by a rectangle), and then add a point on the rectangle
<h3>Plane I contains line EL</h3>To do this, we draw a plane I (represented by a rectangle), and then draw a line on the rectangle
<h3>Plane A, B and C are collinear</h3>This means that a line passes through points A, B and C or in other words, points A, B and C are on the same line
<h3>Lines x and y intersect at a point M</h3>This means that point M is a common point on lines x and y or in other words, point M lies on both lines
<h3>Plane A and R intersect at line JI</h3>This means that line JI lies on both planes
