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

Instructions: Find the measure of the indicated angle to the nearest
SVETLANKA909090 [29]

To find the indicated angle, we can use one of the three main trigonometric functions: sine, cosine, or tangent.

Remember: SOH-CAH-TOA

Looking from the angle, we know the adjacent side and the hypotenuse. Therefore, we should use cosine to solve.

cos(x) = 12/36

x = cos^-1(12/36)

x = 71 degrees

Hope this helps!
