Answer:
x = pi, 3pi, 5pi etc
x = -pi, -3pi, -5pi etc
Step-by-step explanation:
cos^2 x + 2 cos x + 1 = 0
replace cos x with m
m^2 + 2m +1 = 0
solve by factoring (this is a^2 +2ab+b^2 = (a+b)^2 where a =m and b=1)
(m+1)^2=0
take the square root of each side
m+1 =0
m=-1
now replace m with cos x
cos x = -1
take arccos of each side
arccos cos x = arccos (-1)
x = pi, 3pi, 5pi etc
<h2>Answer:</h2>
13.391 ft
<h2>Explanations:</h2>
The schematic diagram of the given question is shown below;
The height of the tree is expressed as:
H = h +5
Determine the value of h using the SOH CAH TOA identity

Determine the height of the tree

Hence the height of the tree is 13.391ft
Money Required for making 1 Sandwich that is Cost Price of 1 Sandwich = S Dollar
Selling Price of 1 Sandwich = 20 % more than Cost Price S
= S + 20 % of S
= 
=$ 1.20 S
= $(S + 0.20 S)
Selling Price of 73 Sandwiches = $ 73 (S + 0.20 S)
The expression $73(S+0.2 S) →→ Selling Price of 73 Sandwiches
