The measure of one angle is described as twelve more than four time a number .

12 + 4n

∠a = 4n + 12

To determine the measure of the angle described, we need to translate the given information into an algebraic expression.

Let's assume that the number is represented by the variable "x".

According to the information given, the measure of the angle is described as "twelve more than four times a number." In algebraic terms, this can be written as:

Angle measure = 4x + 12

Now, if you have a specific value for "x," you can substitute it into the expression to find the measure of the angle.
