Answer:


\boxed {\boxed {\sf x=6}}

Explanation:

An isosceles triangle has 2 equal base angles and 2 equal legs.

In this triangle, 16 must be the base, because the base angles are adjacent. Therefore, the legs are 35 and 5x+5. They must be equal to each other.


35=5x+5

Solve for the value of x by isolating the variable on one side of the equation.

5 is being added to 5x. The inverse of addition is subtraction. Subtract 5 from both sides of the equation.


35-5=5x+5-5 \\ 35-5=5x\\30=5x

x is being multiplied by 5. The inverse of multiplication is division. Divide both sides by 5.


(30)/(5) =(5x)/(5) \\(30)/(5)=x\\6=x

The value of x is 6.
