Question

choose an action to perform.
select the angle labeled with a variable expression. use the value
you calculated for x to determine its measure.
6x - 10 + 2x = 90
x = 12.5
enter the measure of the angle.
degrees

Explanation:

Step1: Substitute the value of \(x\)

Given \(x = 12.5\), substitute into the expression \(6x-10\).

$$6x - 10=6\times12.5-10$$

Step2: Calculate the multiplication

$$6\times12.5 = 75$$

So the expression becomes \(75-10\).

Step3: Calculate the subtraction

$$75-10=65$$

Answer:

\(65\) degrees
