No because  a regular polygon is a two-dimensional shape with straight sides that all have equal length. A regular decagon is a 10-sided regular polygon. As it turns out, there are only three regular polygons that can be used to tessellate the plane: regular triangles, regular quadrilaterals, and regular hexagons.

Answer:

<h2>MN</h2>

Step-by-step explanation:

If ΔLMN ≅ ΔXYZ, then corresponding angles and corresponding segments are congruent:

∠L ≅ ∠X

∠M ≅ ∠Y

∠N ≅ ∠Z

and

LM ≅ XY

MN ≅ YZ

LN ≅ XZ

Answer:

C = 37.6991

Step-by-step explanation:

The equation for the circumference of a circle is given: C = π · d

where, d is the diameter of the circle.

Plug in the value of d = 12 and use the π button on the calculator.

C = π · 12

C = 37.6991

A dog is standing 12 feet from a tree looking at a bird in the tree. the angle of elevation from the dog to the bird is 50°. how
jasenka [17]
The distance of the bird from the ground will be given by:
tan θ=opposite/adjacent
θ=50°
opposite=h
adjacent=12 ft
plugging in the values in the formula we get:
tan 50=h/12
thus
h=12tan50
h=14.301 ft
=14.3 ft

Answer:

first one:

Area of a circle = π*r²

diameter (they gave) = 30ft

radius = diameter/2 = 15ft

π*15²= 706.85834705770347865409476123789‬

to nearest tenth= 706.9 ft

second question:

circumference = 2*π*r or d(diameter)*π

diameter = 30ft

30*π = circumference = 94.247779607693797153879301498385‬

in terms of π = 30π
