Answer:
The answer is 45 degrees.
Step-by-step explanation:
The minimum degree of rotation by which this octagon can map onto itself is 45 degrees.
A full rotation is 360°. One eighth of a rotation is degrees, and each one eighth of a rotation will map a regular octagon onto itself.
Answer:
4p + 12
Step-by-step explanation:
p + p+2 + p+4 + p+6 = 4p + 12
Answer:
Step-by-step explanation:
It would be 48+48+x=180, since 3 angles in any triangle will always measure 180, by definition of a triangle. I guess you could also do 2(48)+x=180, but the first equation just makes it more intuitive I guess. The reason why this works is because since 3 angles must equal 180, the missing angle, x, must be the value of 180-48-48, since that would be the remaining value needed to make a triangle

Answer:
x= 40.33
Step-by-step explanation:
In geometry, alternate exterior angles are a pair of angles that are on the outer side of two parallel lines but on opposite sides of the transversal. In other words, they are the angles that are not on the same line as the parallel lines.
The alternate exterior angles are always equal in measure. This is because when a transversal intersects two parallel lines, it creates two pairs of alternate exterior angles, and each pair of angles is supplementary to each other (meaning that their measures add up to 180 degrees).
In this case:
a° = b°
Since,, the alternate exterior angles are always equal in measure.
3x+17 = 138
subtracting 17 on both sides
3x + 17-17 = 138-17
3x = 121
dividing both sides by 3.
The value of x is 40.33 which proves that r is parallel to s.
Answer:
c) 40.3
Step-by-step explanation:
According to the Alternate Exterior Angles Theorem, when two parallel lines are intersected by a transversal, the angles that are exterior to the parallel lines and on the alternate sides of the transversal are congruent.
Therefore, if lines r and s are parallel, then a° = b°.
To find the value of x that proves line r is parallel to line s, solve a° = b° for x.
Therefore, the value x that proves line r is parallel to line s is:
B.$1320
C.$1100
D.5250
The answer is C. 1100
