Answer: X is equal to 7.

Step-by-step explanation:

First off, the angle must measure 90 degrees for it will be a right angle.

So set an equation to find the value of x.

6(2x + 1) = 90.

First, simplify the distributive property.

6(2x + 1) = 6 * 2x + 6 * 1 = 12x + 6.

So now you have the equation 12x + 6 = 90.

Now we need to isolate 12x in order to continue with finding the value of x.

Use the inverse operation to do this. The inverse operation of +6 is -6.

12x + 6 - 6 = 90 - 6.

12x = 84.

Now we must divide by 12 on both sides to get what x equals.

12x/12 = 84/12.

x = 7.

So x is equal to 7.
