Question

1. solve for x.

(2x)° 48°
x = ______

Explanation:

Step1: Identify angle - sum property

The two angles $(2x)^{\circ}$ and $48^{\circ}$ are supplementary (form a straight - line), so their sum is $180^{\circ}$.
$2x + 48=180$

Step2: Isolate the variable term

Subtract 48 from both sides of the equation.
$2x=180 - 48$
$2x = 132$

Step3: Solve for x

Divide both sides of the equation by 2.
$x=\frac{132}{2}$

Answer:

$x = 66$
