Θ =
![\frac{360}{10}](https://tex.z-dn.net/?f=%20%5Cfrac%7B360%7D%7B10%7D%20)
= 10
a = 18cos36
b = 18sin36
Area = 10×
![\frac{1}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20)
×18sin36×18cos36 = 770.36
Answer:
184
Step-by-step explanation:
The prime numbers between 40 and 56 are 41, 43, 47, and 53.
Add the prime numbers.
41 + 43 + 47 + 53
= 184
Answer:
s = 6 cm
Step-by-step explanation:
The area (A) of an equilateral triangle is calculated as
A =
( s is the length of side )
Here A = 9
, thus
= 9
( multiply both sides by 4 to clear the fraction )
s²
= 36
( divide both sides by
)
s² = 36 ( take the square root of both sides )
s =
= 6
For 1/2 a rotation it would be half of 360
