What is the measure of an exterior angle of a regular 7-sided polygon?

round to the nearest tenth of a degree

Step-by-step explanation:

# The sum of the exterior angles of any polygon is 360 degrees.

# We can deduce that if the heptagon(7-sided polygon) is regular, then all the exterior angles are congruent.

# As a result measure of each exterior angle is 360/7 i.e., 51.428571

Hence measure of an exterior angle of regular heptagon is nearly 51.4°

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
