See the attached picture with letters to better understand the problem

we know that
the figure is a regular hexagon

A regular hexagon has:

<span>Interior Angles of <span>120°
</span></span>so
in the triangle ABC
BC=2 units
∠ABC=30°
∠BAC=60°

tan 30°=AC/BC
solve for AC
AC=BC*tan 30°-------> AC=2*(√3)/3
<span>Apothem is equal to AC
</span>Apothem=(2/3)√3

the answer is
(2/3)√3

Dev makes 600 cakes. 18% of the 600 cakes go to a hotel and 2/3 of the 600 cakes go to a supermarket. Calculate how many cakes h
sveticcg [70]

Answer:

92 cakes.

Step-by-step explanation:

First, find how many cakes is 18% of 600 by multiplying .18 by 600 which equals to 108 cakes. 2/3 of 600 is equal to 400. Then, add 108 and 400 = 508. Subtract this number from 600 and you have your answer.

What is the exact value of cos 105 degrees?
Fittoniya [83]
Your answer is C c:

First, split the angle into two angles where the values of the six trigonometric functions are known. In this case, 105, can be split into 45+60 (cos (45+60)) 

Use the sum formula for cosine to simplify the expression. The formula states that cos (A+B) = - (cos (A) cos (B) + sin (A) sin (B)).

The exact value of cos(60) is 1/2. So multiply 1/2 to cos (45) - sin (60) times sin (45).

The exact value of cos (45) is the square root of 2 over 2 

(1/2) ⋅ (<span>√2/</span>2) - sin (60) <span>⋅ sin (45)
</span>
Value of sin (60) is <span>√3/2

</span>(1/2) ⋅ (√2/2) - √3/2 ⋅ sin (45)

exact value of sin (45) is √2/2

(1/2) ⋅ (√2/2) - √3/2 ⋅ √2/2 

all that equals √2/4 - √6/4
