Variables: x, y, z (we should multiply them and put them together )
Then coeffitions, we should multiply them
Now put coeffitions before variables:
Answer:
The correct options are;
1) The shape maps unto itself after a rotation of 270 degrees
2) The smallest angle of rotational symmetry is 90 degrees
3) The shape maps unto itself after a rotation of 180 degrees
Step-by-step explanation:
We note that the shape of a cross which consists of two equal members (segments) bisecting each other at right angles such that when a member is placed vertically upright, the other member will be horizontal, therefore we have;
After rotation by 90 degrees, the vertical member will become horizontal and vice versa
After rotation by 180 degrees, the vertical member will become horizontal and vice versa again
Similarly, after rotation by 270 degrees, the once vertical member will become horizontal and the horizontal member will become vertical
There are 6 sides so that means that the angles add to 180(6-2) = 180(4) = 720 degrees
So let's add up the angles and set that result equal to 720. Then solve for n
Note: I'm starting at the angle n and working counter-clockwise
(n)+(140)+(151)+(62)+(135)+(n+6) = 720
n+140+151+62+135+n+6 = 720
2n+494 = 720
2n+494-494 = 720<span>-494
</span>2n = 226
2n/2 = 226/2
n = 113
So the final answer is n = 113
3/8 is the amount of her garden that is planted in carrots.
