The exterior angle of a regular polygon is 15 degrees how many sides does it have

Komok [63]

The formula to use is
n = 360/E
where
n = number of sides
E = measure of exterior angle

In our case, E = 15 so
n = 360/E
n = 360/15
n = 24

This regular polygon has 24 sides

Geometry question on finding x.

Dmitrij [34]

Answer:

$x =63^o$

Step-by-step explanation:

Given :-

$\text{ $\overline{MN} $ and $\overline{ML}$ are tangents .}$

We know that the tangents are perpendicular to the radius at the point of contact . And here OLMN is a quadrilateral. Also we know that , the angle sum property a triangle is 360° .

According to question :-

$\implies x + 117^o + 90^o +90^o = 360^o \\\\\implies x + 297^o = 360^o \\\\\implies x = 360^o - 297^o \\\\\implies x = 63^o$

Hence the value of x is 63° .
