6. <u>substitution</u>
7. definition of <u>alternate exterior</u> angles
A; any shape with four sides w/ a parallel side across from each other is co soldered a rectangle. It’s not b because quadrilaterals just have to have four sides, not be rectangles, it’s not c because a square has to have equal length sides and not all rectangles do, and it’s not d because a parallelogram only has one set of parallel lines, but a rectangle has to have two.
Answer:
9 in
Step-by-step explanation:
For an n-sided polygon, the length of the apothem is ...
a = r·cos(180°/n)
We assume your problem statement is saying the radius is 10 inches. For a hexagon, n=6 and we have ...
a = (10 in)cos(30°) ≈ 8.66 in
Rounded to the nearest inch, the apothem is 9 in.
Answer:
the answer rounded to the nearest hundred is 0.86
Step-by-step explanation:
the full answer is 0.859375
Given:
The point is T(-3,7).
To find:
The image T' after .
Solution:
, it means reflection across x-axis is followed by reflection across y-axis.
If a point is reflected across the x-axis, then
Then point is reflected across the y-axis. So,
Therefore, the coordinates of point T' are (3,-7).
