Answer: X is equal to 7.
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.
