The value of x from the given expression is; x= -2/3

<h3>Solving one-variable equations</h3>

The given expression is;

  • 23(9x+6) = 6x + 4.

Hence, when we expand the equation; we have;

  • 207x + 138 = 6x +4

  • 207x - 6x = 4 - 138

  • 201x = -134

  • x = -134/201

  • x = -2/3

If cos(2/3x+20)°=sin(2x−10)°, find the acute angles of the corresponding right triangle.
adell [148]

Answer:

A = 40°

B = 50°

Step-by-step explanation:

If cos A = sin B, then A + B = 90

So, 2x/3 + 20  + 2x - 10 = 90

      2x + 60 + 6x - 30 = 270

               8x + 30 = 270

                       8x = 240

                          x = 30

2x/3 + 20 = 60/3 + 20 = 20 + 20 = 40

2x - 10 = 2(30) - 10 = 60 - 10 = 50  or  90 - 40 = 50
