If the measure of one interior angle of a regular polygon is 156° , how many sides does it have?
1 answer:
Answer:
<em>The polygon has 15 sides</em>
Step-by-step explanation:
<u>Angles in a Regular Polygon</u>
A polygon with n sides has a total sum of internal angles equal to 180°(n-2). This means that in a regular polygon, each angle measures
The regular polygon's interior angle is 156°, thus
Multiply by n:
Operate:
Reducing:
Solving:
The polygon has 15 sides

Answer:
y= x-4
Step-by-step explanation:
Since we have a point, and the slope, we can use the point slope formula
m is the slope, y1 is the y coordinate of the point and x1 is the x coordinate of the point.
We know that m is 1, y1 is 1, and x1 is 5, so we can substitute them in
y-1=1(x-5)
Solve for y by isolating it
Distribute the 1
y-1=1*x+ 1*-5
y-1=x-5
Add 1 to both sides
y=x-4
Written as an expression, the statement 'the sum of the square of a number and 34' would look like this:
