Answer: Hexagon AGHBGHCGHDGHEGHFGH coincides with hexagon ABCDEF when GH passes through themidpoints of opposite sides; that is, it is a perpendicular bisector of the two sides. HexagonAGHBGHCGHDGHEGHFGH also coincides with hexagon ABCDEF when the line of reflection joins a pair ofvertices opposite one another on the hexagon. There are three perpendicular bisectors and three pairs ofopposite vertices. In all, there are six lines of reflection that will map the hexagon back onto itself.
Answer:
0
Step-by-step explanation:
tan 5
π
Remove full rotations of 2
π until the angle is between 0 and 2
π
. tan π
Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because tangent is negative in the second quadrant. tan 0 The exact value of tan 0 is 0
. Multiply
1 by 0

Answer:
A
Step-by-step explanation:
the rest of the tables have two of the same numbers and it is not a function if it does that.
Answer:
m∠EBC=34°
Step-by-step explanation:
we know that
m∠DBC=m∠DBE+m∠EBC
see the attached figure to better understand the problem
substitute the given values in the formula and solve for x
Find the measure of angle EBC
m∠EBC=(3x+13)°
substitute the value of x
m∠EBC=(3(7)+13)°
m∠EBC=(21+13)°
m∠EBC=34°
