a.40

d.55

The exterior angle is 45°

Option b is correct.

Step-by-step explanation:

Given a stop sign is a shape of a regular octagon

we have to find the measure of each exterior angle.

Exterior angle of a regular polygon is supplementary to its interior angle.

Sum of all interior angles of  N-sided regular polygon can be calculated as

Since it is a regular octagon, so each of the interior angles of octagon are equal that are

Each exterior angle is the supplementary angle to the interior angle

∴ Exterior angle is

The exterior angle is 45°

Option b is correct.

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
