<h2>Part a)</h2>
You can name planes by one letter or using three points belonging to it that are <u>not</u> on the same line.
Another name for plane X could be:
- Plane ABF, Plane BCF or Plane ACF. You may also get different names by reordering the three letters.
<h2>Part b)</h2>
Coplanar means 'on the same plane'.
The points on the same plane as point A are:
<h2>Part c)</h2>
Collinear means 'on the same line'.
Other points on the same line as point C are:
<h2>Part d)</h2>
The line that intersects ED is:
- AC, it can be also named AB or BC.
Answer:
Step-by-step explanation:
Y2 + 72 ÷ x - 12
Putting values of x = 9 and y = 5 in the equation
(5)^2 + 72 ÷ 9 - 12
25 + 72 ÷ 9 - 12
25 + 8 - 12
33 - 12
= 21
To check this answer what you need to do is subtract 21.4 from 56.9 and you get w
45.96 + 1.95b = 387.21
-45.96 -45.96
1.95b = 341.25
/1.95. /1.95
