Find all solution of the following equation in the interval [0, 2pi) No decimals.

Delicious77 [7]

Step-by-step explanation:

<u>Step 1: Add 2cos(x) to both sides</u>

$7cos(x) + 2cos(x) + 9 = -cos(x) + cos(x)$

$9cos(x) + 9 = 0$

<u>Step 2: Subtract 9 from both sides</u>

$9cos(x) + 9 - 9 = 0 - 9$

$9cos(x) = -9$

<u>Step 3: Divide both sides by 9</u>

$9cos(x) / 9 = -9 / 9$

$cos(x) = -1$

<u>Step 4: Find x</u>

$cos^-^1(-1) = x$

$\pi = x$

Answer: $x = \pi$

Please help asap, how do I find the missing variables? (Trigonometry)

Georgia [21]

Answer:

x = 5.333 , y= 9.620764575

Step-by-step explanation:

sin(29)/x = sin(90)/11

x = 11* sin(29)/sin(90)

x = 5.333

(5.333)^2 + y^2 = 121

y^2 = 121 - (5.333)^2

y= 9.620764575
