1 answer:
Valentin [98]3 years ago
8 0

Step-by-step explanation:

3 + \frac{9}{4} = \frac{9}{x+4} \\  \\  \therefore \: \frac{3 \times 4 + 9}{4} = \frac{9}{x+4}  \\  \\ \therefore \: \frac{12 + 9}{4} = \frac{9}{x+4}  \\  \\ \therefore \: \frac{21}{4} = \frac{9}{x+4} \\  \\ \therefore \:21(x + 4) = 36 \\  \\ \therefore \:21x + 84 = 36\\  \\ \therefore \:21x = 36 - 84\\  \\ \therefore \:21x = - 48\\  \\  \therefore \:x =  \frac{-48}{21} \\  \\ \therefore \:x =  \frac{-16}{7} \\  \\  \huge \red{ \boxed{ \therefore \:x = - 2 \frac{2}{7} }}\\  \\

What is the measure of the apothem, rounded to the nearest hundredth of a centimeter?
malfutka [58]

The measure of apothem is 1.75 cm.

The complete question is

The area of the regular octagon is 10.15 cm2.

What is the measure of the apothem, rounded to the nearest hundredth of a centimeter?

<h3>What is an Octagon ?</h3>

A polygon with eight sides , eight angles and eight vertices is called an octagon.

If a is the Side of the octagon.

10.15 = 2(1+√2) a²

a² = 10.15 / [2×(1+1.414)]

a² = 2.10

a = 1.45 cm

Therefore the side = 1.45 cm

A = 8 × (a × h)/2

If we consider  8 equilateral triangles with

a = face of octagon

h = Apothem of octagon

10.15 = 8 × (1.45 × h)/2

h = 10.15 /4/ 1.45

h = 1.75  cm

Therefore the measure of apothem is 1.75 cm.
