The sum of the interior angles of a polygon with $n$ sides is

$180(n-2)$

Since a pentagon has 5 sides, the sum of its interior angles is

$180(5-2) = 180 \cdot 3 = 540$

Since it is a regular pentagon, all sides and angles are the same, so one single angle measures

$\dfrac{540}{5} = 108$ degrees.

Answer:

14.14

Step-by-step explanation:

The diagonal of a square is √2 times the side length.

AC = AB×√2

AC = 10√2 ≈ 14.14

_____

The diagonal of a square is the hypotenuse of an isosceles right triangle. If the sides of that are s and the diagonal is d, the Pythagorean theorem tells us ...

d² = s² + s²

d² = 2s²

d = (√2)(√s²) = s√2

This relation holds for <em>any isosceles right triangle</em>, not just for the diagonal of this square. It is useful to remember.

Tangent WZ and secant WV intersect at point W. Find the value of X. If necessary, round to the hundredths place.

alexira [117]

For the above figure, the formula is,

x² = WY (YV + WY)

WY = 5
YV = 12

Substituting in the above formula,

x² = 5 x (12 + 5)
x² = 5 x 17 = 85
x² = 85
⇒ x = √85 = 9.21954 = 9.220
