Step-by-step explanation:
Using the identity
cosecx = 
and the exact values
cos45° = 
, sin30° = 
Given
cos45° × sin30° + cosec30°
= × + 
= 
+ 2
= + 
= 
(
+ 8 ) ← exact value
≈2.354 ( 3 dec. places )

Answer:
- reflection, then translation
- rotation, then translation
Step-by-step explanation:
When the points designating each triangle are considered in order, they are seen to be in clockwise order. Segment FG is oriented to the west, while corresponding segment VW is oriented to the east. This means the figure could have been rotated 180° or reflected across a point. Either way, some translation may be necessary to align the figures as shown.
Possible transformations include ...
- reflection across a point, then translation (depending on the location of the point)
- rotation 180° about a point, then translation (depending on the location of the point)
___
If one of the triangles is reflected across the midpoint of GW, it will coincide with the other triangle. Hence only one reflection across a chosen point is required. Of course, reflection across a point is identical to rotation 180° about that point. For any other point of reflection or rotation, translation will be involved.
Regular polygon area = n*side^2 / (4 * tan (180/n))
where "n" is number of sides
The formula is dependent on the side^2 term,
So, if we have an octagon that has sides 4 times as large, that means the area will be sixteen times larger.
side^2 = 4^2 = 16
So we multiply 25 cm^2 by 16 and we get
400 square centimeters.
