A branch grows from the trunk of a tree. It makes two supplementary angles with the trunk. What must be the variable of x if you have 76+8x=

76+8x= 180

8x = 104

x = 13

To find the value of x in the equation 76 + 8x = ?, we need more information or an actual value.

If you have a specific number or expression on the right side of the equation, you can substitute it in and solve for x. Without knowing what comes after the equal sign, it is not possible to determine a unique value for x.

Please provide the complete equation or any additional information so that I can assist you further in finding the value of x.
