Answer:

Step-by-step explanation:

Solution for cosx=-3/2 equation:

cos((3*pi)/5)*cos((3*pi)/20) = 0

(60*x^3)/(60*x^5) = 0

What is the value of x

Nesterboy [21]

Answer:

$x = 2$

Step-by-step explanation:

First simplify the equation.

$\frac{7}{9}x -\frac{4}{9} =\frac{1}{4} +\frac{5}{12}$
$\frac{3}{9}x= \frac{3}{12} +\frac{5}{12}$
$\frac{3}{9}x=\frac{8}{12}$
$\frac{1}{3}x=\frac{2}{3}$

Now multiply both sides by 3.

$x = 2$

I hope it helps you. Please choose my answer as the BRAINLIEST.
